B. F. Skinny

B.F. Skinny is a talking rat who appears in JumpStart Adventures 5th Grade: Jo Hammet, Kid Detective. Unlike animal characters from many other JumpStart games, he is not naturally anthropomorphic, but the product of an experiment.

He is the messenger of the whole operation. He delivers Martin's coded messages directly to Jo Hammet at the museum. He calls Jo "lady" other than her real name. He also calls the janitor a "guy with a broom".

Quotes

 * "[H]e can speak English, but latched onto the old comedy routines of the movies we used to watch in the lab. Now he only speaks in bad jokes and tired cliches, but you've gotta love the little guy!" - Martin

Trivia
