What has six legs, two sets of wings, and a zany teacher at the wheel? The Magic School Bus as a tiger beetle! Join the Friz's class and learn amazing insect and spider facts. When Wanda brings her new ladybugs to school, she just wants Ms. Frizzle to give her some hints on caring for her insect pets. Instead, the whole class gets field trip. They find out pretty quickly that lots of insects eat other insects for lunch. And, there is a little issue of spiders, too. Yikes! It might be disgusting, but Wanda has to admit that the world of insect invaders is amazing.
