To celebrate the founding of Walkerville, Ms. Frizzle's class sculpts a stone likeness of its founding father, Captain Walker. But as they add the finishing touches, the statue tumbles down the mountain. Ms. Frizzle turns the bus into a giant boulder... (more) and the kids into rock kids. They bump down the mountain in a desperate attempt to save the statue. By the time they reach the celebration at the base of the mountain, they've been pushed, tossed, sanded, polished, and eroded by water, as has the statue now the size of a soccer ball. The kids are sure they've let everyone down until they look back at the mountain for the surprise of their lives! With Jessica Walter as "Ashley Walker-Club-Dupree."
