is a 400-pound silverback gorilla who shares a communal habitat in a suburban shopping mall with Stella the elephant, Bob the dog, and various other animals.

Ruby is recently separated from her family in the wild, which causes him to question his life, where he comes from and where he ultimately wants to be.
