Animal

What animal always goes to sleep with his shoes on?

It's voice is like a burp, Will swallow with a slurp, You'll never hear it chirp. Kiss it with a wince, Might turn into a prince

A mysterious, fantastic creature, It has one defining feature, And for humans at their worst, In their eyes it's just a horse
