Bunnyman

Bunnymen are Mobs found underground. They spawn from craftable and Naturally generated 'Carrot Houses'. Because Carrot Houses are craftable, presumeably, Bunnymen can also live on the Overground too. Bunnymen are often found fighting fellow underground Mobs. Upon death, Bunnymen drop 2 Carrots and 1 Meat. Bunnymen will become allied to the player in return for Carrots.

Behaviour
Bunnymen will attack the player on sight, providing they are carrying Meat in their inventory. This includes Monster Meat. Bunnymen behave in much the same way as Pigs, except they will attack you without provocation.
