"The Magic School Bus" is an award-winning, animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Ms. Frizzle's class is visiting the zoo, which is, according to Tim, the only place in the city where wild animals can survive. To test this idea, Ms. Frizzle turns the class into possums, foxes, and falcons. The kids explore the city as animals and see how wildlife can live in the city.
