Donkey

Donkeys are a species of equine known to inhabit Ponyland and Equestria.

Biology
Donkeys are somewhat similar in dimension to most adult ponies, though with more protruding knees and long tails that end in tufts of fur. The ends of their snouts also tend to be a lighter color than their fur.

It is possible that Donkeys can breed with Ponies, due to the existence of Mules.
