Bender is feeling ill, so the Professor uses a new invention, the F-Ray, to look inside him. He has stolen Amy's watch, which got lodged in his machinery. Meanwhile, Fry has become addicted to Slurm, a soft drink, and he and Bender use the F-Ray to try and find a golden bottlecap that will win them a trip to the Slurm Factory. They eventually find it and go on a tour of the factory, where they meet Slurms McKenzie, the original party worm. The tour guide refuses to tell them what the secret ingredient is, so Bender, Leela and Fry investigate. They find a door that says 'Real Factory' and discover that Slurm in fact comes from the behind of an enourmous slug called a Slurm Queen. To stop them talking, the queen gives Fry a trough of irresistable Slurm that he will drink until he explodes, puts Leela in a liguid that will turn her into a Slurm Queen and puts Bender on a can-making machine. Fry drags the trought to go and save Leela and they manage to escape. To stop the queen catching them, Slurms parties so hard that he causes a cave-in, killing himself and trapping the queen.

Fry: If only there was some way to see which can had the winning bottlecap...
Bender: What? Sorry I didn't hear you, I was too busy using this F-Ray to look inside of things.
Fry: Wait! I'm getting an idea! ...nope, false alarm ...yes! No! Yes! No! Yes!
