Liz has disappeared and the trail leads to Herp Haven, which is some kind of spa for reptiles. The class decides to lead a rescue mission, on which they learn about reptiles and how they need to move from place to place to be comfortable because they are cold-blooded. Ms. Frizzle turns some of the students into reptiles.

Put your game face on and race into these three athletic adventures with Ms. Frizzle and the gang. Includes: Plays Ball, Works Out, and Shows And Tells.

Ms. Frizzle and the kids are off on an adventure to the rain forest, to find out why Ms. Frizzle's cocoa tree has stopped growing cocoa beans.

Dorothy Ann loves her physics book; Ralphie loves baseball. Ms. Frizzle ingeniously combines the two in a page-hopping adventure through Dorothy Ann's book to a "Frictionless baseball game." The whole class learns about pushes and pulls in a remarkable day at a thouroughly unique ball game.

As Ms. Frizzle leads the way, the class takes a journey through Arnold's digestive system, a pulsating excursion through Ralphie's bloodstream, and an exciting exploration through the Ralphie Robot to learn about bones, joints and muscles.
