Mr. Trapples is an old tattered teddy bear belonging to Fred Jones, Jr. which he has formed a strong attachment to. He speaks to it as if it were alive much like a child might talk to their stuffed toy, but it could also possibly suggest a mild form of Schizophrenia.
Mr. Trapples is a small, blue stuffed bear with a lighter blue stomach and a gray belly button. It's missing its left eye and has a hole on its ear, as well as one on its arm where stuffing sticks out. In a similar fashion to its owner, Mr. Trapples wears an orange bow tie.
