The episode starts out when Squidward walks outside and sees a tiny shell on his front lawn. He believes that it ruins the appearance of his lawn, so he kicks it onto SpongeBob's lawn on purpose. Suddenly, SpongeBob pops out of his window and sees the shell. He also believes that it ruins the appearance of his front lawn, so he gets his "reef blower" (an underwater version of a leaf blower) out of his garage. He turns it on, much to the annoyance of Squidward. Squidward plugs his ears and SpongeBob struggles to blow the shell away. After failing attempts, he angrily blows a large column of sand onto Squidward. To fix this problem, SpongeBob blows the sand off, which irritates Squidward's eyes. SpongeBob peers over at his sidewalk and sees a pile of sand. A subtitle "You" appears as SpongeBob points at the pile (no dialogue is heard). He then sucks the pile of sand into the reef blower, which begins to malfunction. The sand and a few mechanical gears blow out. So, SpongeBob unzips the reef blower and puts them in himself. The reef blower sneezes.
When the reef blower refuses to start, SpongeBob pulls the cord to an extreme distance and before finally starts. However, this causes it to suck in all of the water in the ocean. The reef blower then explodes, returning the water and leaving piles of sand all over Squidward's lawn, while SpongeBob's lawn is perfectly clean. Satisfied, SpongeBob gets out of a pile of sand and then goes back inside, while the shell lands on Squidward's nose.
The episode was originally going to have dialogue, but the recording equipment broke and the episode was rewritten to be silent.
