In this final adventure, Whip and his four friends, Bobi, Pition, Fentruck, and Ezra, work in a science lab and a nerdy science toucan invents a time machine. Whip and the gang test it, and it glitches as a bomb sending them back to the time of the dinosaurs. They are stuck back in time to help a herd of herbivores battle the mighty T-Rex, Gish. Will this be enough to reactivate the time machine and zoom back to the present? Whip is to be married soon to his fiancée, Imogene (formerly known as Princess Zelda of the Vips).
