The episode starts with Squidward going outside, only to spot a shell on his lawn. He kicks the shell onto SpongeBob's yard to keep his own clean, but it turns out SpongeBob is also very protective of his lawn, and gets out a reef blower from his garage to get rid of it, the noise of the machinery making Squidward irritated.
SpongeBob, struggling to blow away the shell, ends up blowing it so hard sand comes out and lands on Squidward. SpongeBob comes to Squidward and blows off the sand that landed on Squidward as well as his face. Seeing that there is a huge pile of sand on his yard, SpongeBob sucks it up, but the reef blower starts to break apart and throws out sand.
SpongeBob opens up the zipper behind the reef blower and puts the excess sand that was thrown out in there. He tries to start it again but it doesn't work. This prompts SpongeBob to pull the handle of the reef blower very far. Once he feels he's far enough, he lets go and quickly zips through the distance he went back onto the blower. SpongeBob starts sucking up the entire ocean, causing Squidward to almost suffocate, but quickly shoots all the water sucked up back out again. The episode ends with SpongeBob happy that his lawn is clean, while Squidward's lawn is filled with sand.
