Billy becomes obsessed with his Troggie friend Yucky's wart, and decides to transfer it onto his body without Yucky's permission, but guilt starts to kick in.
Plot[]
While picking berries, Billy encounters a small Troggie named Yucky, named so after the fact that Billy's breath smelled bad. They quickly become friends and Yucky shows off a wart he has growing on his arm. Billy becomes obsessed with it and reasons that Yucky would not understand its significance. Billy opts to steal it for himself so that he can play with it. Using one of his devices, Billy sneaks into Yucky's cave dwelling and zaps the wart onto his arm. He then spends the following day playing with it and showing it off to a clearly uninterested Zeke.
Yucky suddenly shows up crying with Marsha translating that he is missing his wart. Zeke points out Billy's new wart which shocks Marsha and Yucky. Billy tries to cover by saying that Yucky's wart had two hairs while his only has one (he ran upstairs and quickly snipped the extra hair off). Billy suggests that he may have lost his wart near a volcano and sadly leaves. Billy then goes to his room to take a nap and has a nightmare that Yucky went to an actual volcano and fell to his doom. Waking up in total remorse and fear, Billy runs out of the house in an effort to save his friend.
Billy arrives at the volcano, but believes he is too late and uses his device to remove the wart and toss it into the lava. Billy rolls down the hill and finds Yucky crying at a tombstone he made for his wart. Happy with tears, Billy reveals that he stole his wart out of jealousy and begins hitting his head on a tree. The unusual fruit on it squirts juice onto Billy's head causing him to grow a giant wart that he and Yucky begin playing with. Yucky then takes Billy's device and starts chasing him in an effort to have it transferred to him.
