This article is related to content of the Base Game. There may be a version for the "Spaced Out!" DLC, see Critter (Spaced Out).

Critters are aliens that lay eggs and some species produce materials and/or drop meat when dying. Ranching can be used to increase the number of critters, eggs, and materials. Some critters have different morphs which consume different foods, live at different temperatures, or produce different products.

Critters in DLC[ | ]

See: Critters in Spaced Out

Common traits[ | ]

Most critters share the following traits:

  • Are not aggressive (with exception of Pokeshell, which will attack anything if there are any of their eggs nearby).
  • Occupy one tile and can crawl into narrow spaces (except adult Pokeshells).
  • Will die when subjected to temperature extremes (specific range depends on species). Tend to migrate to livable temperature zone accessible to it.
  • Can live in any atmosphere including Vacuum, yet will drown in liquids (but will try to escape), with exception of Pacus and Pokeshells.
    • Common critters, such as hatches, will drown in
      • 1) a liquid tile with a mass difference less than 50kg to the element's critical mass(the maximum mass for a natural liquid tile), i.e. a water tile with over 950kg of mass, or,
      • 2) any liquid environment that is over 2-tiles deep, i.e. in a 10g water tile with any amount of petroleum on top of it.
    • On the other hand, Pacus will be reduced to the flopping state in absence of water(or some other liquids they can live in).
  • Both wild and tamed critters age, lay eggs, and have a capped life expectancy (with exception of Morbs, those have no life-cycle, and Gassy Moos, which lay no eggs).
  • Juvenile critters take 5 cycles to grow into an adult.
  • A wild critter does not need a 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.
  • Tamed critters lay tamed eggs. Babies won't starve and don't require a diet. Once matured, tamed critters need a stable food supply to survive.
  • Wild critters usually always stay happy, if they have enough space.
  • Resource conversion can range twentyfold depending on critter status. Happy and Tamed Critters have 100% production, Wild has 25%, Glum has 20%. Wild and Glum has only 5% production rate. See also: Metabolism
  • Can't use ladders for pathfinding purposes, but can pass through opened pneumatic doors, and walk on opened horizontally placed doors. Drops only at the moment a door opens. Can get confined when a tile is built on top of them or were idle in a closing door.
  • Can arrive as a care package by Printing Pod (except Morbs and Gassy Moos).
  • They drop meat or whatever material when they die, no matter of how this happens (being killed by a duplicant, dying of old age, drowning, ...). Killing a Juvenile critter will grant the same amount of output.

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.
  • Babies can't jump tile gaps, or up/down.
  • Non-aquatic critters sometimes jump into a puddle of liquids that's less than 1 tile thick.

  • Pufts, Gassy Moos, and Grubgrubs (Spaced Out) all have the highest Minimum Space Requirement (16 tiles), so fewer can fit in one room at a time.
  • Cuddle Pips have the smallest Minimum Space Requirement (4 tiles, four times less than a Puft), so many can comfortably live in the same room.

Confined[ | ]

"This critter is trapped within a door, tile, or confined space" "Sounds uncomfortable!"

The Critter is in a Room that is too small to meet the Space Requirements of that type of Critter (shown above). This debuff reduces Happiness by 10 and reduces Reproduction Rate by 100%, regardless of any other Reproduction Rate increases.

  • This debuff overrides the Crowded and Cramped debuffs, and is seen as the most severe of the three.

PuftConfinedAndNotPuftFeelingFinePuftFeelingConfined

  • Left: a room with 16 tiles (4x4) that is comfortable for a single Puft.
  • Right: a room with 12 tiles (3x4) that is not comfortable for any Pufts.

Crowded[ | ]

"This critter isn't comfortable with so many other critters in a Room of this size."

The Critter is in a Room where the sum of all space requirements based on the amount of Critters inside exceeds the room size. The effect reduces Critters reproduction rate to 0% preventing further overpopulation. .

  • It will calculate Crowding by counting the total amount of Critters in the same room (itself included), and multiplying that number by it's personal Tile Space Requirement to compare to the room size (See Examples).
  • If the final number exceeds the current room size, that Critter will feel Crowded.

APuftShineBugAndCuddlePipPuftCrowdedCuddlePipSatisfiedTextShineBugWildCrowdedText

  • In this first example (above) both rooms have a space of 28 tiles (4x7).
  • The Cuddle Pips is not Crowded, as the total of 3 Critters multiplied by it's Space Requirement of 4 equals 12, much less than 28.
  • The Shine Bug is Crowded, and while only one other Critter wouldn't crowd it, having three total exceeds the room's space. (3x12=36>28)
  • The Puft is Crowded, as only one Puft would be comfortable in a 28 tile room, and more would overcrowd it (2x16=32>28).
    • Since the Shine Bug would be comfortable with one less Critter in the room, it only gets a -1 Happiness debuff
    • Because the Puft is not comfortable with having any additional Critters, it gets a -2 Happiness debuff (-1 for both critters)

Cramped[ | ]

"This Room will become too crowded once all nearby Eggs hatch" "The selected Critter has slowed it's Reproduction to prevent further overpopulation."

The Critter is in a room where the amount of Critters inside including the Critter Eggs in the room, multiplied by the Critter's Space Requirement is greater than the current size of the Room. The effect reduces Critters reproduction rate to 0% preventing further overpopulation.

  • While very similar in calculation to Crowded, but this de-buff only decreases Reproduction Rate, yet can still affect Critters that are Crowded
  • It als includes Critter Eggs to the total Critter count instead of just the amount of Critter in the Room.
  • As stated above, Confined overrides the Cramped status, as it already affects Happiness and Reproductive Rate.

ConfinedPuftCrowdedCrampedBugConfinedPuftTextBoxShineBugWildCrowdedCramped

  • The room in the picture is 12 tiles large (3x4), and does not meet the minimum room requirements of the Puft, making it Confined.
  • Note that Shine Bugs are usually comfortable in 12 tile rooms, but the addition of a Puft causes Crowding, and the Egg causes Cramping.

Exceptions[ | ]

  1. Morbs are ignored when calculating the required room size.
  2. Shove Voles will count towards the stable overcrowding, however, they do not care about any amount of overcrowding themselves.
  3. Cuddle Pips consider each egg type to only require 4 tiles of space
