Jeffy's parents are worried about him after he almost drowns in the bathtub, so they decide to get him swimming lessons. They hire a swimming instructor who uses unorthodox methods, including feeding Jeffy a large amount of hot dogs before getting in the pool and using a floatie shaped like a boat. The instructor also tries to get Jeffy to swim by putting his paralyzed dog and then his cat in the pool, but both attempts end in failure. Eventually, the instructor's plan to flip over the floatie and get Jeffy to swim doesn't work, and Jeffy is left traumatized. Despite the failure of the swimming lessons, Jeffy's parents try to get him to take a bath again, but he insists on using the floatie to feel safe.
