The Culture Vat (sometimes called the cultivator) is an extremely important, slightly transparent, emerald green block that is part of the last step needed to create any extinct animal Eggs or Embryos. It is the only way to obtain any Prehistoric Mob, aside from living fossils.


The Culture Vat is a block that acts as a light source when it is placed down. It is slightly transparent in the middle. It is a dark green on the edges, and a light green on the inside. It has a tint of green where it is see-through. At the top is a gray hole, which is presumably how the DNA is placed inside. At the bottom it is gray and has a large red button.

Animal Embryo

When DNA or a Plant Fossil is put inside and sufficient fuel is used, eventually a white embryo will form inside the Culture Vat, which will move in place (you may have to right-click the Culture Vat to make it appear). There are currently two versions of this: the Animal Embryo and the Plant Embryo.


To use the Culture Vat, you must have any form of DNA or Plant Fossil from an Analyzer. Once you obtain this, you must put the DNA in the top left spot, and fuel (see below) in the bottom spot. Milk is the best option as it only takes one bucket for a single cultivating. After many minutes and at least half a stack of meat, the DNA will turn into an Animal Egg, Embryo, or Prehistoric Plant which can then be either hatched, put into a mammal, or placed on grass or dirt, respectively.

Be wary of failures (see below)!


To create, you need modern day DNA as fuel for the Culture Vat, such as:

  • Bio-Fossils
  • Raw/Cooked Farm Animal Meat
  • Fish
  • Eggs
  • Milk
  • Rotten Flesh


To craft the Culture Vat, you will need four blocks of glass, three iron ingots, a cactus green dye, and a bucket of water, placed in the configuration below. Don't worry; you will get back the bucket.

Failuresaurus in Sunlight after Culture Vat Failure

There is a generally uncommon chance that at any given moment during cultivation of an animal, the cultivator may explode and spawn a Failuresaurus, or a creeper. However, the explosion doesn't cause any damage to surrounding blocks or players. Instead, the cultivator will be destroyed and leaves a water source block in its place, while spawning various items around it. When a plant embryo fails, instead of one of the aforementioned mobs you get a failure plant.
