| Character Information
Rocky is covered in fuzzy orange fur that is not easily pulled off. He has a striped nose and wears a black t-shirt, pants, but no shoes. Rocky is animated in CGI, but is designed to move like and resemble a Muppet.
Rocky does a lot of jobs around Elmore Junior High, ranging from janitor to cook and many more. He's a good friend to pretty much all the kids and loves to hang out with them, especiall Gumball. Rocky is also not very bright, much to the shame of his parents, who also aren't very pleased about his career choices either. Rocky's also not very good with women, much to his dismay.

- Rocky's t-shirt is a reference to the band AC/DC and their famous logo. It is seen in Gumball and Darwin's room.
