Basic Information[]

This article tries to cover all there is to know about growing Crops and farming other stuff in Creativerse. You can grow Crops and cook Food ever since the "Farming" update R22 was implemented on September 16th 2015 ("Home, Home on the Range").

4 types of Crops exist in Creativerse: Wheat, Turnips, Crisphead Lettuce and Horned Melons. Seeds can be obtained by collecting (Savannah) Tallgrass and by harvesting Crops in the wild that spawn there in time, and then placing these Crops into a Processor.

Tilled land has to be created by using a Plow on Dirt, Mud and/or green Grass. Each tilled grass needs to be placed adjacently to a unit of Water, Mineral Water or (only a little) Bog Water and into suitable biomes/areas (not too hot, not too cold, not too high up, not close to Bog Water pools), without any regard to lighting.

Seeds can then be placed on this tilled land. Seeds and Seedlings can optionally (but not necessarily) be fertilized with Pigsy Droppings in order to reduce growth time. After 50-90 minutes (real-life-time, even when you are offline), the Crops will have grown. They will not ever wither, but the best harvest can be achieved by pulling them within 24 hours.

You cannot only grow Crops in Creativerse, but also 3 types of trees from Saplings, all 3 types of Mushrooms from Spores, Beeswax from Queen Bees as well as Flowers on tree Leaves - you can find paragraphs about these other types of "Farming" further below.

"Farming" can also refer to making Creatures spawn on purpose in order to kill them, perhaps even let them be killed automatically by teleporting them into traps where they will drown. This ambiguity is covered at the end of this article.

Depending on interpretation, "Farming" could also include cooking Food from Crops and/or taming Pets to harvest from.

Consuming Food is not necessary for your player character to survive, and Creativerse does not even feature a hunger bar. However, Food can still be consumed to grant your player character specific buffs like taking less damage from heat, cold, poison or corruption, to take less to no fall damage, or even to transform certain damage over time effects into a healing over time effect.

Food grants buffs for either 7,5 minutes (all Bread types) or 15 minutes (all other cooked Food) to player characters that will help surviving environment challenges and attacks of Creatures in Creativerse. Buffs will reduce or negate elemental and fall damage, grant healing and bonuses on health and/or stamina. Food buffs can be "stacked" with the buffs that are granted by Potions, Mushrooms and the like. It is possible to have 7 buffs active at the same time.

Even though Pets cannot starve, you can feed all types of cooked Food to Creatures that you have tamed, since you can only harvest from your Pets after you have fed them. You should preferably always provide every Pet with its exact favorite Food type in order to receive the best harvest from the Pet (for example: if a Pet prefers ordinary Sandwich, it will only provide you with a meager harvest after you have fed it with a Turnip Sandwich).

Obtaining Seeds[]

5 types of Crops can be found on all game worlds in Creativerse:

Seeds for these Crops can be obtained by processing any obtained Crop in a Processor, which does not require any crafting recipe to be unlocked. 1 Crop will be processed into 2 Seeds each.

Turnips, Crisphead Lettuce and Horned Melons grow over time in the game world and have to be processed into Seeds at first in order to be multiplied by farming.

Wheat on the other hand does not grow anywhere in the wild, but can only be grown by players. Wheat Seeds can be obtained as an occasional extra harvest when collecting Tallgrass or Savannah Tallgrass with the ArcTek Gauntlet. Excavators will not yield any Seeds though.

Turnips can most often be found in Swamplands, but also in Woodlands, Forests and around Mountains, rarely even in Tundras on Dead Grass.

Crisphead Lettuce can be found in Woodlands, Forests occasionally in around Mountains, rarely in Tundras on Dead Grass and also rarely in Swamplands. They might even spawn on green blocks of Grass that players place(d) into other biomes like Savannahs.

Horned Melons can solely be found in Jungle biomes growing on Detritus. They have not yet been experienced spawning on any player-made structure made from Detritus.

When Capture Blocks are used on Crops (no matter if player-grown or spawned in the wild), only their according Seeds will be part of the building kits for the created Blueprints afterwards - since Crops themselves cannot be placed into the game world, they can only be put into the slots of display containers, can be fed to Pets and can be consumed from the quickbar with right-click (by default).

Tilling Land[]

Seeds can only be planted on tilled soil - one patch of Seeds can be placed on either a block of Dirt, green Grass or Mud that has to be tilled with a Plow in order to transform into tilled land.

For tilling you will need a Plow. The crafting recipe to craft a Plow will be unlocked by crafting/taking an Obsidian Mining Cell. Crafting the Plow (with 2 Stone Rods, 2 Obsidian (ore) and 2 (blocks of) Stone) is one of the requirements to unlock the crafting recipe for the Cooking Station.

To use it, you have to equip the Plow by right-clicking on it which will make it go into the tool-slot next to your character's portrait. By pressing TAB you can cycle between weapon, mining cell and tool. Choosing the plow will "ready" it like it was a weapon, and you can use it on a tillable block by left-clicking and holding down the left mouse-button for 1,5 seconds.

As said, you can till Dirt, Mud and/or green Grass, but not Dead Grass, Rocky Dirt, Canyon Floor or Savannah Grass blocks. If a block is tillable, then your cursor will turn cyan-blue over that block when you have a Plow equipped and point your cursor at a natural block. You can place blocks of Grass, Mud and/or Dirt yourself and then till them, they don't have to be "naturally" generated blocks.

However, when picking up a block of tilled land, it will turn into common Dirt in your quickbar or inventory.

Even if you aim at the side or underside of a block, the Plow will always plough the upper side of the block. Tilled land also can't be rotated to the side or upside down by usual means. It can be rotated sideways though to make it easier for you to perceive where each block ends and then next one starts.

Also the direction of the stripes of tilled land depends on the position of the player character when facing the block that is tilled. So if you till a block while your player character faces direction N-S (as seen on the compass), the result will be a tilled block with stripes in N-S direction. This can be used to create creative patterns.

You can place plowable blocks into different biomes in order to till them there and create your farm nearly anywhere, however it cannot be too cold, too hot, too high up or too close to a significant amount of Bog Water.

Crops do not need light to grow in Creativerse, so you can grow them successfully underground too. The Lava layer is unsuitable though, simply because it is too hot there with a very high base temperature even with no Hardened Lava or liquid Lava close by. Even if you cool down tilled acres with a Snow Blower, this will not solve the problem.

Biomes with a bit of Snow or Ice might be suitable anyways, as long as you remove all cold-emitting blocks within a certain proximity so that the tilled land will not be cooled down. Canyons for example are suitable, but not if there's Ice or Snow.

If the biome is too cold, like any areas or artificial biomes on high altitudes over 150 blocks, then Seeds will stay fallow no matter what, even if you place heat-emitting blocks, liquids or objects adjacently to tilled blocks.

Swamplands and artificial biomes with too much Bog Water won't do either, they are seemingly poisonous.

Sometimes, you cannot grow Crops in surface areas where Seeds will stay fallow for no apparent reason; this most often happens in Forests. In this case, you can try growing crops higher up or further down on acres created by yourself from Dirt or Grass (or Mud if you wish so) with some Water underneath or next to it.

The Plow will lose a little bit of durability (or power) with every usage until it will fall apart. One plow can till 100 blocks of land before it breaks. At present, equipment and tools like Plows cannot be repaired.

The most common layout for tilling land :

(T = tilled land, W = water)


Alternatively you can place Water (or Mineral Water) directly under blocks of Dirt or Grass, which enables you to plant more seeds. In this way you can build acres in any creative shape you like. As a beginner, it's even easier if you build acres from blocks of Dirt or Grass directly over the surface of a lake or the Ocean.

Planting Seeds[]

To plant Seeds, put them into your quickbar, select that and simply put the (patch of) Seeds onto the tilled land with right-click. Only one Seed of a stack will then be planted each. You can place Seeds like any common type of block by selecting their quickslot and either clicking your right mouse button (by default) or typing the number key for the quickslot twice - while pointing your cursor at the spot where you want to plant the Seed.

You should plant Seeds on tilled land as quickly as possible, otherwise idle tilled land is going to turn to Dirt (even former Mud will do that) after a short while, and then perhaps into green Grass if another block of Grass is close... Take care not to stand directly on a block of tilled land when trying to plant a Seed on it.

Tilled land can be re-used (seemingly unlimited times) if you just plant new Seeds quickly enough right after harvesting Crops that you have grown there before. However, tilled land cannot be moved elsewhere, because it will turn into Dirt if you pick it up.

If you want to keep the tilled land from changing into Dirt because you still have to process Crops into Seeds, you can place a torch or any other block or placeable item on the acres after tilling or harvesting until you can then replace these placeholders with Seeds.

Since update R46 ("Galactic"), it should not longer be possible to re-use the same Seeds repeatedly by using Block Phasers to re-sow them automatically again and again right after harvesting the grown Crops.

Watering Seeds[]

Creativerse Wheat Seeds watered001.jpg

If no moisture is near, the Seeds that you have placed on tilled land will stay "Fallow" (written in red letters at the bottom of your screen over the quick-slots if you look at the seeds) and won't grow no matter what.

Water, Bog Water or Mineral Water can be used to water seeds. Just take care to use only a few units of Bog Water, since too much Bog Water will render all Seeds fallow within a certain proximity.

The moisture needs to be placed directly adjacent to the block of tilled land, at least corner touching corner. This block of moisture for Seeds can also be one block under/below or above the tilled land.

Water does not need any Power Cell to be scooped, for Mineral Water a Diamond Mining Cell is needed.

For beginners it might be a good idea to simply till land right next to lakes or to build an acreage directly above the water surface (starting from the shore is the easiest).

Seeds, Saplings, Mushroom Spores and Queen Bees can even be planted underwater and will grow into Crops, trees, Mushrooms and Beeswax there. However, only 1 block of Beeswax will grow as long as all surrounding spaces are filled with liquid and such already "occupied".

Fertilizing Seeds[]

It is not necessary to use fertilizer to make Crops grow. Fertilizing Seeds or Seedlings will only speed up their growth. In general Wheat grows fastest, Horned Melons grow the slowest of all crops.

Wheat needs approx. 50 minutes (real-life-time) to grow from seeds into ripe plants, even if you're offline. Lettuce needs about 60 minutes, Turnips not much longer (ca. 61 minutes), Horned Melons need ca. 90 minutes until they're ripe. Fertilizer will only reduce these growth times for ca. 15 minutes.

Currently, only Pigsy Droppings can be used as a fertilizer, and this is only available from Pigsy Pets.

So you need to tame Pigsies or Night Pigsies, Night Hoglets, Ghost Pigsies or Polturpigsies, then feed them, preferably their exact favorite type of Food like shown in their Pet window, and afterwards harvest from them in order to receive this fertilizer.

Pigsy Droppings can be used by being placed into the quickbar, then by selecting the according quickslot, point your cursor at the Seeds or Seedlings, finally use right-click or press the according number key twice (by default). You have to aim directly on the Seeds you have planted to make them grow into Seeslings immediately.

Fertilizer can also be used on Seedlings (first stage of growth) to spurt their growth into Sprouts.

After Crops have reached this growth stage, Sprouts will no longer accept fertilizer. So don't wait too long with fertilizing your Crops if you want to spurt their growth.

Under fitting conditions, each planted/placed patch of Seeds will grow into a Crop that can be harvested as soon as the Crop is "ripe". This is the optimal time for a harvest, and is reached within 50 minutes (real-life-time) up to 90 minutes depending on the Crop. Seeds will grow into plants even if you go offline.

Seeds will stay fallow if the conditions are not to their liking (read more about this below) - usually if moisture is missing (or has frozen into Ice), or because the biome/area is too hot, too cold or too high up for farming, or maybe too much Bog Water is nearby, like in Swamplands. Fallow Seeds cannot even be fertilized. 

Light "Level"[]

In Creativerse, Crops do not need light to grow. You can grow plants underground or inside of buildings in complete darkness too if you like.

Just make sure that the place is not too high up, that the surrounding temperature is not too hot or too cold, and also that Water or Mineral Water or a little Bog Water is (placed) adjacently to each block of tilled land.

Harvesting Crops[]

You can harvest Crops as soon as they are "ripe" (You can see the description of the grow stage of Crops at the bottom of your screen above the quickslots when looking at the Crops.)

As mentioned above, Wheat needs approx. 50 minutes (real-life-time) to grow from seeds into ripe plants, even if you're offline. Lettuce requires about 60 minutes, Turnips not much longer (ca. 61 minutes), while Horned Melons will take ca. 90 minutes until they're ripe.

If Pigsy Droppings were used as a fertilizer either on the Seeds after you have placed them, or on Seedlings (the first stage of growth of Crops), then this will usually only reduce the growing time of Crops by ca. 15 minutes. 

In order to harvest, pull the Crops with your ArcTek Gauntlet by using left-click in the same way as you would take/mine any common block in Creativerse. You might want to de-equip your Power Cell first so you won't accidentally pull any tilled land additionally.

It is not recommended to use Excavators, because they will only return 50% of the harvest, and they are rather hard to place in such a way that they will not remove tilled land together with the Crops.

If you wait longer (ca. 24 hours of real-life-time), then the crops will turn into "Grown" crops, and will give a little less harvest than during their optimal "ripe"-stage. Crops will not ever wither in Creativerse.

Lettuce reaches its "grown"-status the fastest, Horned Melons take the longest to be all grown.

WARNING: if growth conditions change while Crops are still growing or have grown, then the Crops will revert back into fallow Seeds. This might happen if the temperature of the environment increases or drops, if the moistening liquid is removed or freezes, if too much bog water is placed nearby, etc.

Only rarely, Crops will stay just as they are for a while if have already reached their "grown" stage (or even "ripe"), even if soil and water are removed.

Every 60 seconds, the game will "check" if the requirements for growing seeds are (still) met. This counter starts as soon as the Seed is planted (tested as of update R30 with Horned Melon seeds). So if growth requirements are changed, Crops might not react for up to one minute and then suddenly revert back into - fallow - Seeds.

Fallow Seeds[]

Seeds will stay "fallow" if they cannot grow into Crops, such as when no unit of moisture (or only an unsuitable liquid like Molasses, Tar or Corrupted Water) is touching the block of tilled land that you have placed the Seeds onto. Sometimes, Seeds can be "misplaced" by clicking too fast, so that they will either land on ground blocks next to tilled land or float in the air - even if moistened, Seeds will still not grow into Crops if not on tilled land.

Seeds will naturally stay fallow on the Lava layer or any other biome that makes a heat meter/scale show up, as it is too hot for them there to grow into plants.

Seeds also won't grow in cold, snowy and icy environments, neither on tilled land that is too high up in the sky (over 150 blocks, type // to learn about your exact coordinates).

Please note that Seeds will usually stay fallow in cold environments even if you heat up the tilled land by placing Hardened Lava or heat-emitting objects adjacently and moisture them with Mineral Water that won't freeze as quickly as Water would.

Crops might also not grow when a pool of Bog Water is nearby - but also in other areas of Swamplands biomes that are rather far away from Bog Water pools, as well as in biomes close to Swamplands.

Fallow Seeds cannot be fertilized, so don't worry about wasting Pigsy Droppings.

If Seeds won't grow in a specific surface area, you can try planting them right underground in the Fossil layer or Stalactite layer (or even in the Corruption layer) or higher up in the sky; but not too high, not over 150 at least. As mentioned; Crops do not need illumination, therefore they can grow just fine underground on tilled land with some suitable moisture adjacently (Water, Mineral Water, Bog Water), even on the Corruption layer.

As a side note: Seeds and Crops at any growth stage cannot be burnt or corrupted.

Other types of "Farming"[]

Growing Beeswax from Queen Bees[]

You can grow Beeswax from Queen Bees if you place them on blocks of Wood or most tree Leaves.

Queen Bees cannot be placed on Dark Wildwood Leaves, Shorewood Leaves and Snowy Elderwood Leaves, Shorewood, Corrupted Wood, Corrupted Leaves, Shorewood Husks, Cacti or any type of Logs or Flowers.

If you do this in a fitting environment, one Queen Bee block will transform into up to 6 blocks of Beeswax (into all "free" directions that are not occupied by any other block, liquid or the like) within 4 RL hours - or 15 minutes less if you fertilize the Queen Bee with Pigsy Droppings. Like Seeds and tree Saplings, Queen Bees will also "grow" into Beeswax even if you're offline and no player character is close.

Please note that Beeswax will only grow in suitable biomes and areas. Queen Bees will stay fallow when placed in areas that are too hot, too cold, too high up or simply unfitting for Beeswax to grow (like many areas in Swamplands). Fallow Queen Bees cannot be fertilized either. Light is not necessary for Queen Bees to transform into Beeswax though. Like usual, Beeswax does not require any Power Cell to be "harvested". While Queen Bees are flammable, Beeswax is not. Neither of both can be corrupted.

Growing Mushrooms from Spores[]

Since update R59 on January 31st 2019, you can now grow Red Mushrooms, Brown Mushrooms and Glowing Mushrooms from Mushroom Spores. Mushroom Spores can be obtained as a random extra harvest when you pick Mushrooms of any kind. Moreover, all 3 types of Mushrooms can be processed into their according Mushroom Spores 1:1 in a Processor (which does not require any crafting recipes to be unlocked).

Mushroom Spores can be planted (placed) on top of blocks of Dirt, Grass, Mud by simply placing the Spores there. If the Mushroom Spores are planted in a suitable environment with a unit of Water, Mineral Water or Bog Water adjacent to the block they are placed on, they will grow into Mushrooms after 10 minutes real time.

Mushroom Spores can be fertilized with Pigsy Droppings too, and will then turn into grown Mushrooms immediately. Just one growth stage exists for Mushrooms. Mushroom Spores will stay fallow in unsuitable biomes that are too cold, too hot, too high up or the like. Like with Seeds and Queen Bees, light is not required for Mushrooms to grow.

Harvesting player-grown Mushrooms (including Glowing Mushrooms when grown by players!) does not require any Power Cell to be equipped. One grown Mushroom (batch) will turn into 6-10 units of Mushrooms in your inventory, rarely with one additional batch of the according Mushroom Spores on top of that.

Additionally to that, Red Mushrooms can "regrow" (spawn over time) ever since the earliest Creativerse update R2, however they will only spawn in very small numbers and only in areas that are not lit by artificial light sources. Red Mushrooms will most often spawn in areas where all original occurring Red Mushrooms have been plucked, usually on blocks of green Grass. They do not seem to grow on player-made arenas that were built in other "natural" biomes, but Red Mushrooms can still rarely appear on Dead Grass in Tundras.

Mushrooms are not flammable and cannot be corrupted either.

Growing Trees from Saplings[]

3 kinds of trees can be grown by players from tree Saplings: Ashenwood Saplings, Cragwood Saplings and Elderwood Saplings. These Saplings can be obtained as a rare extra harvest when collecting blocks of Ashenwood, Cragwood and/or Elderwood, but also when collecting Ashenwood Leaves, Cragwood Leaves, Elderwood Leaves and/or Snowy Elderwood Leaves. Saplings cannot be created in a Processor.

Trees can only grow successfully when you placed tree Saplings on blocks of Dirt or green Grass (and Elderwood Saplings on Snow Cap too). Neither plowed land nor Mud is suitable for tree Saplings. 2x2 or more tree Saplings can be placed together and will sometimes grow into thicker trees (up to 4x2 max. up until now), but sometimes into 2 trees on top of each other instead. Saplings do not require any moisture nearby in order to grow (different from what outdated ingame tips might claim), but they will only grow well "under sunlight", so preferably on the surface.

Saplings will need 15-16 RL hours to grow into trees, fertilizing with Pigsy Droppings will only shorten this time very little, at about 15 minutes. Please note that tree Saplings will only grow in certain Biomes, like in Forests, Woodlands or in valleys between Mountains. Elderwood Saplings can grow well in Tundras, other Saplings won't. Unfortunately, there will always be areas that are not to the liking of tree Saplings even in otherwise suitable biomes, so that Saplings will stay "fallow" there. If Saplings stay fallow, no trees will grow from them no matter what. Fallow Saplings also cannot be fertilized.

Player-grown Ashenwood trees look like umbrellas; they only rarely feature Moss as part of their stems and branches, but will rather often have Red Flowers amongst their leaves. Player-grown Cragwood trees also look like umbrellas; they occasionally feature Vines(-covered Wood) as part of their stems (most often on their base), and often Yellow Flowers will hide amongst their leaves. Player-grown Elderwood trees look like "layered" pine trees and will often have Blue Flowers on them, however, no Rimecones on or around them.

Sometimes, Beeswax can also be part of player-grown trees as soon as they pop up fully grown, while in time, additional Flowers will spawn on their Leaves, as well as Queen Bees that will then transform into Beeswax under suitable conditions. In order to harvest the blocks that occur on player-grown trees, no Power Cell is necessary for any of this.

Corrupted trees cannot be grown, but can be created by throwing Corrupt Bombs on any uncorrupted type of tree made of uncorrupted natural Wood and Leaves blocks (not Shredded Leaves though, nor any other type of crafted/processed blocks or shapes). Moss-covered and Vines-covered Wood blocks will turn into common Corrupted Wood when being corrupted. Snowy Elderwood Leaves can be corrupted by Corrupted Water and/or Corrupt Obelisks too. Flowers, Beeswax and hanging Vines cannot be corrupted. Wood, Leaves, Moss and Flowers are flammable (also Logs and Queen Bees), even corrupted Wood and Leaves. Vines, Vines-covered Wood blocks and Beeswax are fireproof though. Tree leaves can be destroyed by a Gauntlet Smash.

Growing Flowers[]

Also many Flowers will continually spawn on blocks of Leaves ingame over time, so you can build "farms" from leaves for them. This works well with Red Flowers on Ashenwood Leaves, Blue Flowers on Elderwood Leaves, Yellow Flowers on Cragwood Leaves and Wildwood Flowers on Wildwood Leaves or Dark Wildwood Leaves. Unfortunately it is much easier to multiply these exact same Flowers by placing them on the ground and picking them up again which will sometimes yield an extra Flower block as additional harvest...

Tundra Flowers and Wildflowers (on the ground in Savannahs) can "regrow" (spawn over time) since update R14, just like Red Mushrooms, however these flowers will only spawn in very small numbers and only in areas that are not lit by artificial light sources. They will most often spawn in areas where all original occurring ground flowers have been plucked, and not outside their endemic biomes. They do not seem to grow on player-made artificial biomes at all.

Wildflowers in Savannahs can be destroyed with the Gauntlet Smash only if at least a Stone Mining Cell is equipped (also Tallgrass, Savannah Tallgrass, Shrubs and Weeds). Weepwood Flowers and Wildwood Flowers cannot be grown, but multiplied by placing and picking them up again. These two type of tree Flowers can be destroyed by a Gauntlet Smash even without any Power Cell equipped. Flowers cannot be corrupted, but nearly all flowers are flammable and can be destroyed by fire.

Creating Ice, Hardened Lava, Coal, Diamond Nodes[]

In a way one could say that Ice (for Slopes so you can create "railways" with Fans) can be "farmed" from Water or Bog Water. You can do so easily by creating a stream of these liquids that you will need to keep warm enough at their source so that they will stay liquid, but cool down at the end or bottom of the stream, so that they will freeze and turn into Ice blocks. This can easily be accomplished on high altitudes if you just keep the one source block of liquids heated, like by placing a Campfire, Fire Pit or Fireplace directly under it.

Hardened Lava can be "farmed" from liquid Lava. You only have to make sure that the source unit/block of liquid Lava is surrounded by hot blocks (Hardened Lava or any items that emit enough heat) so that it will stay liquid. Let it flow down into a cooler area, where it will automatically turn into blocks of Hardened Lava.

When using this term, then even Coal Nodes and Diamond Nodes can be "farmed". Please refer to the articles Making Coal and Making Diamond for this.

Farming Creatures and Treasure Chests[]

You can also "farm" many Creatures and Treasure Chests by building artificial Biomes from specific blocks and under certain conditions that will make them spawn, albeit a bit random and in rather small maximum numbers.

Treasure Chests will only spawn in complete darkness on specific blocks, but somehow randomly and not too many of them within a specific range: Diamond Treasure Chests will spawn on all Corrupted Blocks, Iron Treasure Chests will spawn on Lava layer blocks like Hardened Lava and Igneous Rocks, Obsidian Treasure Chests will spawn on Stalactite layer blocks like Siltstone.

Stone Treasure Chests are a bit fickle, they will most often spawn on Bedrock, sometimes on Limestone and certain Ore Nodes, but most often only on the Fossil layer and not on artificial biomes on the surface. Wood Treasure Chests will only spawn during night times and in complete darkness on any type of typical surface ground blocks like green Grass, Savannah Grass, Dead Grass, most tree Leaves, Detritus, Sand and many types of Canyon blocks.

As for Creatures, please note that those spawned with Mob Spawners cannot be tamed and will not drop any loot when killed. Some Creatures can only be summoned with either Haunted Idols or Trog Traps and many of them will drop special loot. Additionally to all of that, you can make most (not all) wild Creatures spawn too though, but only rather randomly and only under well fitting circumstances.

Many Creatures will only spawn during the day on surface blocks, even on artificial biomes:

Underground Creatures and Night Creatures (some are both) are a bit more demanding:

Please note that placing artificial biomes close to each other might result in only sparse spawns on just a few of these biomes. Also having a Touchstone close by can somehow interfer. Since a certain maximum number of Creatures is able to spawn within an area, underground Caves and layers have to be considered too.
