Squirrel

The Squirrel is a background critter that cannot harm players and serves as environment flavor. Like bunnies they appear in the forest biome. They only have only 5 health, no defense, and can be damaged by other mobs including the player, which almost always results in their instant death. Ironically, they cannot climb. They only come in one shade; gray. A squirrel behaves like other critters - it seems to do exactly what a bunny or penguin would do (loitering around aimlessly).
