SpongeBob becomes sick with a fever, so Patrick offers to take over SpongeBob's shift while he gets better. Patrick enters the Krusty Krab right after Squidward complains to Mr. Krabs that he cannot cook and serve at the same time. Patrick continues to mess up the orders. The first one he messed up was jellyfish jelly on jam, when it really should have been clams.
Next, Patrick was too busy admiring a photo of SpongeBob when Squidward noticed the Krabby Patties were on fire and extinguished the flames. Patrick is warned by Mr. Krabs that if he loses any more money, he'll break out in a rash. Patrick then trips into a stack of cans. Squidward is annoyed and complains that he cannot stack them up himself. Patrick then falls asleep and Mr. Krabs tells Squidward not to wake him, since this is the most amount of help he can give.
The book ends with SpongeBob returns to work. Mr. Krabs and even Squidward are overjoyed by his return.
