It is a fine day in Bikini Bottom, and down at the Krusty Krab, SpongeBob adds one percent too much mustard to the Krabby Patties. Mr. Krabs is not happy with this, as this excess would lead him to bankruptcy within the next four hundred and eleven years, however, he assumes SpongeBob is an insomniac, so he sends him home to get some shut-eye.
SpongeBob has a hard time sleeping, so he goes to Patrick's house. Patrick tries to help SpongeBob fall asleep by reading what SpongeBob assumed was a bedtime story. However, the story, "The Land of Perpetual Excitement," was meant to get people out of bed, the opposite of SpongeBob's goal. Then, Patrick sings SpongeBob a "lullaby," which is really a wake-up song, as it is sung loudly as the song goes on, with the lyrics stating to "get up" and "be active." Then Patrick gives SpongeBob some "medicine," which turns out to be coffee, and as a result, it keeps SpongeBob wide awake.
After realizing he drank coffee, SpongeBob starts running around and seeing things, such as an anthropomorphic bush, a talking glass of milk, a bunch of Squidwards, Mr. Krabs with mustard releasers as eyes, reflecting the previous day, etc. The next thing he sees is a bird resembling Gary carrying him to a giant version of Patrick and eats him, thinking he is a sponge cake. Inside Patrick, SpongeBob sees a sunrise. He begs it to let him sleep for just five minutes before he meets Sir Cecil the sleep wizard. Sir Cecil puts sleepy dust on SpongeBob, then he falls asleep. When SpongeBob wakes up in Gary's litter box, realizing that the whole thing was a nightmare, he snaps back to reality.
Realizing he is late for work, a very tired SpongeBob goes to the Krusty Krab, only to sleep in a barrel of mustard. Mr. Krabs takes him out of the barrel of ruined mustard, and wonders why he could not sleep. SpongeBob confesses that his "insomnia" got the best of him. Then, he starts crying tears made of mustard. He cries the perfect amount that is needed to be on the patties. Squidward is happy and claims that it is the best day of work ever, because he got to see SpongeBob being forced to cry mustard, as the episode ends.
