Appearance on Supernanny
Although Corey didn't act out as much as Chase, he was very stubborn. During Observation, he ran out of the house to find a friend to play with (because he was so bored at home). He also whines, cries, and talks back.
When Chase destroyed his clay model he was very upset but then he got an apology from Chase. He has a friend named Adam.
