Critters are aliens that lay eggs, and some species produce materials and/or drop meat when killed. Ranching can be used to increase the amount of critters, eggs and materials.

Meat This creature can be found crawling around in cavities in the Caustic Biome. They are able to cling strongly to any surface, and will freely wander the full perimeter of whatever chamber they are in. They are not hostile and are quite mobile, inevitably wandering away from any chamber they are not trapped in.

Meat Floating/hovering critter. Its movement is based on invert pyramid shape, moves center to top, left then right, follows bubbles of contaminated air, prefers going up. Sucks in the closest air bubble, goes up into top of room/chamber on borders of gases then spits out slime. Can follow its own slime consuming again. Won't go under water, but can enter a stream of water from below or from the side (and then die).

Common traits[edit | edit source]

All critters share the following traits:

  • Are not aggressive, including Hatches dug out.
  • Being subjected to temperature extremes (exact range depends on species) causes death.
  • Both wild and tamed critters age and have a capped life expectancy.
  • A wild critter does not need diet. Once tamed they will begin to lose calories and starve if not fed after a number of cycles. A tamed critter with "glum" debuff loses calories slower than a happy tamed critter.
  • Can live in any atmosphere including Vacuum, except Pacu.

All critters except for Slickster and Pacu share the following traits:

  • Can drown in liquids ( but seem to try to escape )
  • No awareness of danger: the critters will not move away from a source of superheated gas, will not escape a stream of liquid that kills them and so on

Hatch and Morb, as walking critters, share the traits:

  • Can walk, jump across 1 tile gaps, climb diagonally 1 tile, and jump up diagonally 1 tile to left/right and 2 tiles up/down
  • Can't use ladders
  • Are smaller than Duplicants and can crawl into 1 tile openings
  • Can sometimes jump into liquids
