The show revolves around the adventures of Denver, the last dinosaur - a Corythosaurus - who was released from his egg by a group of multicultural modern California teens: Jeremy, Mario, Shades, Wally, and Casey, along with tag-along older sister, Heather. The kids taught Denver the finer points of skateboarding and other pastimes while protecting him from concert promoter Morton Fizzback who wanted to use the dinosaur to make money. /
