Episode Title:
Donald and the Wheel.
Episode Description:
Two "spirits of progress" are observing the potential inventor of the wheel. These spirits are never seen aside from their auras. One of these spirits is an adult (voiced by Thurl Ravenscroft) and is accompanied by his beatnik-talking son (voiced by Max Smith). The elder is trying to explain the importance of the wheel to his son. They observe a caveman (portrayed by Donald Duck) trying to haul his supply sled up a hill and into a cave. Donald is then chased out of the cave by a tiger. He gets away, but the tiger tumbles down a hill wrapped around a rock. The spirits tell Donald that this should be the inspiration for his invention of the wheel...
