I've decided to create some more sheep character to add to the story, and right now I have Pom's father and some guard.

Birchbark: A gray, portly little guy that is very skittish. Although he's as easily frightened as his daughter, he often makes stupid choices and goes out to observe animals (which often leads to his daughter having to 'save' him.) As you can tell, he is based on Professor Birch.

Starry Night: If a sheep could be intimidating, Starry fits the bill. He's not going to let anyone get by the gate that he guards, and he is very tough (not to mention rather good-looking).

I hope to build on them as the game comes out.
