Unicorn is the titular deuteragonist of Go Away, Unicorn!.
He is voiced by Chris Diamantopoulos.
He is a nutty, fun-loving party animal. With a horn on his head and a song in his armpit, he is always looking to make any time a good time. In fact, his horn looks like a permanent party hat ... without the chinstrap.
Unicorn has decided that Alice is his new best friend and he's going to spend every waking moment with her.
Unicorn is also Alice's best friend.
