Carlos and Phoebe can't decide if spiders are cool or creepy. Then, the kids are magically transported into a drive-in movie about a giant praying mantis. When a mad general takes Liz prisoner to use as mantis bait, Mrs. Frizzle turns the Magic School Bus into a spider. Together, the kids must try different methods for rescuing Liz and trapping the bad guys. In the process, they learn many fascinating facts about different kinds of spiders, including trap-door spiders and web-spinning spiders. They gain a new respect for nature's best trappers. As Mrs. Frizzle says, "The spider that snares the best, fares the best!"
