Jenny (XJ-9) Wakeman thinks her house is haunted. SpongeBob, Jimmy, Timmy and B.O.B. then come to see if anything is wrong. Then Sheen, Chester and Patrick come in and Sheen does a song to the sky spirits so the spirits will get out of Jenny's House. SpongeBob, Jimmy, Timmy and B.O.B. find out it's still haunted but Sheen, Chester and Patrick think it's a new ghost.
SpongeBob, Jimmy, Timmy and B.O.B. decide it's there turn and then Sheen, Chester and Patrick leave. SpongeBob, Jimmy, Timmy and B.O.B. think they figured out the sound that's coming from Jenny's snoring but the sound was actually from the sewer. SpongeBob, Jimmy, Timmy and B.O.B. used a T.N.T. to show the ghost that they mean business.
The sewer covering hits the roof and SpongeBob and Jenny check if there's any sound. The sewer covering lands over SpongeBob and Jenny making them fall down into the sewer. SpongeBob and Jenny decide to look around the sewer.
They soon find a creature in the dark (not a ghost) and try to escape from it. Jenny figures out it's afraid of her snoring and they soon find out it's an alligator named Roger. Jimmy, Timmy and B.O.B. come and they tie up Roger, but let's him go.
They soon make friends with Roger and SpongeBob complements Jenny. Sheen, Chester and Patrick were going to find the ghost but Roger came out and they ran away.
