The Magic School Bus: Going Batty teaches interesting facts about different kinds of bats. In the process the children, their parents and of course the school bus are transformed into bats. This book does explain the wherefore behind Ms. Frizzle's magic bus and her apparent ability to brainwash the children and their parents into going along on each of her potentially dangerous field trips. Ms. Frizzle is a vampire. Sure, by the end of book Ms. Frizzle has brain washed everyone into ignoring the fact she was acting like a vampire but I like the pat explanation to the entire series. On a more serious note, the book does have many interesting bat facts. It teaches about echolocation, how bats fly, what bats eat, where bats live and so forth. Bruce Degen did the illustrations for the book and they are cute and not too scary, even when Ms. Frizzle is at her most vampirish.
