Sheep

Who is Sheep?
Sheep is the main character of the Cartoon Network show Sheep in the Big City. In this, he was, literally, a sheep in a city, who was being hunted down by the villainous General Specific. (For a lazer that was powered by sheep. Yeah.)  In the Spice series, Sheep appears as a bit character, appearing sporadically throughout the series. (Like the Kool-Aid Man, Special Agent Oso, Perry the Platypus, Flapjack)etc.

Spice in Space
Sheep makes his debut during the Gary Oak auditions, serving as the host. Since he can only say "Baa," he is subtitled. After (usually) only saying Baa once (his catchphrase) the subtitle creates a full panel of speech. He is considered to be more like Gary Oak than any of the other contestants (Especially Tim the New Guy,) but he will not audition.
