Description
Likes to feed on grass all the time and wants everything for himself. It is also really peaceful, no killing allowed! It is bad in food campaigns, good in item campaigns.

It's generally recommended to unlock Goat in an Ultimate Universe Challenge. You'll need to make the creations necessary for the Divinity Generator by hand, after which it's straightforward.
