It's Wrinklerump's first winter alone, and he needs a cave! He should have listened to mother, who warned him not to dally around. But just as she feared, Wrinklerump would rather go sightseeing than work on finding a cave. Now Wrinklerump needs to buckle down . . . before it's too late! Kids will have fun following Wrinklerump's sightseeing shenanigans on the illustrated map of Yellowstone, and they will also discover why it's a good idea to exercise self-control.
