Plot
SpongeBob is taking another driving test, when he accidentally crashes into the lighthouse, causing all the storage to fly out. SpongeBob tells Mrs. Puff he'll compensate for this and does several things for her, but she compromises by telling him to clean up the lighthouse, and afterwards goes inside the boating school to listen to rock music.

SpongeBob cleans up all the stuff and puts them in several boxes, which get packed into one smaller box. He then cleans the lighthouse itself, until eventually all he has to clean the lantern. However, he starts hearing ghost sounds and after opening the door and a box falling out, he gets scared and bounces down the stairs, and eventually hits the small box and causes a muddle of stuff again.

It turns out the ghost was actually a stray snail, who SpongeBob names Louie. He tries to clean the lighthouse, but Louie ends up distracting him, so he ties him to a boat. However, he escapes from that, so he tries to trap him in a box using a canned Krabby Patty as the lure. Unfortunately, Louie tricks him into getting trapped into a bigger box, and after getting out of that box using leftover Krabby Patty to make him stronger, Louie is nowhere to be found.

He eventually finds him up where the lantern is, but Louie shrieks at him and starts attacking him. SpongeBob ends up hitting the lighthouse's light, causing a reflection that tricks a group of guys into thinking they are giant monsters.

Eventually, their ruckus causes the lighthouse to tip over and start rolling through town, destroying everything in its path. It eventually makes its way back to the boating school, with everything ending up being organized as it lands in its position.

SpongeBob finds out that Louie was trying to protect his babies instead of stopping him from cleaning, and after that, Mrs. Puff arrives and is happy that the lighthouse is completely cleaned. However, she also realizes that the lighthouse destroyed town after a group of citizens complain to her.
