Back to the Future

S03E12 Rocks and Rolls

In honor of Walkerville's founding, Ms. Frizzle's class creates a stone statue of its founder, Captain Walker. Just as they complete their masterpiece, the statue unexpectedly rolls down the mountain. In a frantic bid to rescue it, Ms. Frizzle transforms the Bus into a giant boulder and the students into rocks, allowing them to tumble down the slope in pursuit of the fallen statue.
