They take her home and she makes the toys' head turn and twist till all the fluff inside breaks out, burns the posters Homer places on the wall and eats and spits a bird in his face.

Luann and Kirk get worried as he hasn't come back at home, and Kirk starts busting the wall trying to find him. The police find his bike near the woods, while Kirk places letters on the wall to see if he's in another dimension and he can communicate with them.

Since Milhouse is gone, Luann confesses she's having an affair, and Disco Stu comes down the stairs revealing it's him. Milhouse sends an SOS with the letters but due to the problems they're having they send him and his lights "in his room".

At the Simpsons home, Lisa gets a call from Milhouse, but once she says she doesn't like him as a boyfriend, he hangs up. Lisa goes to the Starcourt Mall, which sign gets invaded by rats to become the Ratscourt Mall.

He could decide he could live the life of a man that was going to die that day, so Homer chooses a football player's body. He goes to Marge and she loves the new body, but he ruins it in one night. Bart and Marge convinces him to try uperintendent Chalmers as the next body.

At Springfield Elementary, Homer makes Principal Skinner give Bart all As and twist his nipple till its deep purple, and then goes to his house just to see he makes very little money and changes again, but Marge has had enough.

Selma and Homer sneak Kang out in a waste container full of rats, but Burns finds them. Kang bites off Smithers head and knocks out Burns, with Barney driving the trio out in his car. Mr. Burns and the military follow, but his driver is shot as they flee to Mt. Springfield. Thinking they're safe, Kodos arrives with a ship but a shooting takes place and Selma is hit in the stomach.
