Bunny

Little is known about the elusive snow bunny. These shy creatures spawn only on Ice worlds -- sometimes from ragged maws and other times randomly in caves -- but their habits are a mystery. Fast-moving and evasive, bunnies do not affect the player in any way. Killing one drops Fur into inventory, and causes the bunny to emit an extraordinarily hilarious and satisfying death scream.

Trapping a bunny counts towards the Trapper achievement.
