The Magic School Bus - Rocks and Rolls - Ep. 39

The class is sculpting a statue of their city's founder, Captain Walker. He left instructions on how he wanted it sculpted in the form of a poem. They interpret the meaning--he wants it sculpted without the use of hands--a little too literally. However, it breaks off the top of the mountain, and falls down. Ms. Frizzle turns the bus into a rock and follows. Water erosion reduces the statue to its head by the time they reach the bottom. Desperate to get to the ceremony, the bus cracks open a dam of rocks that has formed and slides down the mountain. However, they found that somehow they made the mountain into a statue of Captain Walker's head and realize that he had wanted it sculpted through erosion!
