Bones

The Bones modification enriches the Nether with diversity by adding several types of rare skeletal creatures to it. Players will encounter four new types of mobs: skeleton sheep, skeleton pig, skeleton cow, and skeleton chicken.

Each of these creatures can be bred using the meat of their regular living counterparts. The skeleton sheep has an interesting feature — if fed rotten flesh, there's a chance it will regrow its skin, which can then be collected to obtain mutton. The skeleton pig, like a regular pig, can be ridden, but it moves faster and requires a pork chop on a stick instead of a carrot on a stick for control. Skeleton chickens lay various useful items instead of eggs, such as charcoal, fire charges, and gunpowder.
