Bunny

The Bunny is a benign background character that could not harm players, well, most of the time. Bunny has only 5 health, and can also be damaged by other mobs. Player can harm bunnies after defeating Wall of Flesh.

Bunnies will mainly spawn in the middle third of the above-ground world, and only on ordinary Grass. They can also spawn in outer parts, but only if a house is present.

During a Blood Moon, or when hit with Vile Powder, Bunny will turn into Corrupt Bunny, which have much more health and is aggressive.
