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. The class laughs at Phoebe when she suggests they make a butterfly into their new team mascot. But are butterflies as wimpy as the kids think? Ms. Frizzle certainly doesn't think so. She takes the class on a whirlwind adventure to unmask what a 'bog beast' is, and they find out just how tough butterflies can be.
