Squirrel

The Squirrel is a background character that cannot harm players. Squirrels 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 Squirrels can't climb. The Squirrel only comes in one shade; Grey. The squirrel is like other passive mobs... It seems to do exactly what a bunny or penguin would do.
