Sussie is a chin with arms, googly eyes, and a blue plaid dress with white shoes. She has no hair, unlike most characters on the show and is in Miss Simian's class.

Sussie is shown to be a little odd, and also somewhat obnoxious. In The Ghost, she throws up her hot cocoa because of Gumball's stinky breath and in The Party, Penny and Masami give her an annoyed look as she chewed her food sloppily. She apparently likes eating - she is shown eating throughout Rachel's entire party. Despite this, Sussie is apparently good friends with some of the cheerleaders, since she was sitting with
them in The Party.
