Episode Title:
The Busasaurus.
Episode Description:
This is the cartoon version of The Magic School Bus In the Time of the Dinosaurs. This episode's main aim is to show that dinosaurs weren't all terrifying monsters, like movies often make them out to be. The only period seen is the Cretaceous Period (all periods are visited in the book,) which is obviously due to time constraints. In this episode, the kids visit Ms. Frizzle's old friend, Dr. Carmina Skeledon at a dinosaur dig. Dr. Skeledon lets Arnold see a fossilized dinosaur egg as the kids are leaving, and he still has it when they go back in time. An Ornithomimus steals the egg, and both Arnold and Phoebe chase after it. The rest of the class is left to find them, and in the end, Arnold squares off with a Tyrannosaurus Rex after being grown. The episode played a part, albeit a minor one, in spreading the popular misconception that dinosaurs were cold-blooded. (They are thought to be warm-blooded ancestors of today's birds.) In a line regarding the word "dinosaur" meaning "terrible lizard", Dr. Skeledon describes them as reptiles.
