Spike is a rebellious student who became Robbie Sinclair's best friend on Dinosaurs, although he often gave Robbie fairly dubious advice. He was introduced as a semi-regular in the second season, beginning with "How to Pick Up Girls." In the sitcom tradition of the Fonz and Eddie Haskell, Spike continually mooched food and referred to Earl as "Mr. S." His nickname for Robbie was "Scooter." Spike's notable accomplishments included serving with the Pangaean army during the pistachio conflict, demonstrating how to hotwire a car at the Bob LaBrea High School talent show, getting Robbie into (and out of) the Scavengers gang, and introducing Robbie to swamp music.
