One sunny day, Squidward walks outside and looks upon his immaculate front lawn, free of debris save for one tiny shell. Finding its presence unsightly, he nonchalantly kicks it onto SpongeBob's lawn. SpongeBob pops out of his window and sees the shell. Also keen to keep the appearance of his lawn pristine, he gets his "reef blower" out of his garage and turns it on. The noise annoys Squidward, who plugs his ears as SpongeBob struggles to blow the shell away.
After a few failed attempts, SpongeBob applies more force and accidentally blows a large pile of sand onto Squidward and his lunch. To fix this problem, SpongeBob blows the sand off first Squidward, then his plate of kelp, but gets some sand in Squidward's eyes. After clearing Squidward's face, SpongeBob peers over at his sidewalk and the pile of sand now atop it.
More determined to clean his yard than ever, SpongeBob sucks the pile of sand into the reef blower. The yard is cleared, but the blower malfunctions and spits out the sand along with a few mechanical parts. Undeterred, SpongeBob unzips the reef blower and puts the debris in himself. Upon trying to restart the blower, however, it fails to operate.
SpongeBob takes the starter rope and pulls it as far as it can possibly go. Once stretched to its limit, SpongeBob lets it yank him back and the motor restarts. The resulting suction proves so great that it vacuums up all the water in the ocean, leaving Squidward suffocating. The engorged reef blower soon bursts, releasing the water and a large amount of sand.
His yard miraculously clean, SpongeBob heads back inside, leaving Squidward to his fate: his yard covered in sand piles, buried under one himself, and the tiny shell falling gently onto his nose.
The episode was originally going to have dialogue, but the recording equipment broke and the episode was wholly rewritten to be silent.

"Reef Blower" aired as part of the pilot show after the Kid's Choice Awards on May 1, 1999. Unlike a majority of the episodes, this episode segment is paired with "Help Wanted" in that there are no commercials in between. The title card for this episode pops up as soon as "Help Wanted" finishes.
This later happens with other three-episode groups.
