Benjamin Franklin "B. F." Skinny is a male rat character who appeared in JumpStart Adventures 5th Grade: Jo Hammet, Kid Detective.
B. F. Skinny is a regular-sized white rat who stands on two legs and has long arms and human-like hands. His body is triangular. His legs are virtually nonexistent - the corners of his body simply end in disc-shaped paws. He has a thick snout and a huge pink nose. His eyes have blue pupils and black eyebrows that usually fly above his head. He wears shirt cuffs despite not wearing a shirt, and also a red bow tie. He has a thick pink tail and rounded ears with pink insides. He possesses a visible belly button and knobby elbows represented by swirls.
B.F. Skinny gained the personality of a vaudeville entertainer after latching onto old comedy routines from the movies he used to watch in the lab, but has no short-term memory to convey simple thoughts, which resulted in him forgetting a lot of things. He later left town and became a national talk-show phenomenon.
B.F. Skinny often has nicknames for the people he meets, such as calling Jo "lady" and "kid" and calling the janitor a "guy with a broom".
