It's one hour after midnight and the three mice are still awake. Their mother has left them to go looking for food. The temptation is too great and they go wandering down a hole only to find exploring is not a piece of cake! (The episode retells the nursery rhyme of "Hickory Dickory Dock." The story was adapted from the tale of "Hickory, Dickory, Dock" in L. Frank Baum's "Mother Goose in Prose.")
