In the Krusty Krab, a woman fish steps over and files a complaint about something wrong with her Krabby Patty. It has a sea urchin in it and Squidward is very freaked out by this. He tries to smash it with the register, but ends up getting the urchin on his nose. He tries to smash the urchin again, but falls out of the register, with the urchin still on his nose. SpongeBob takes the urchin off his nose and takes it to his workplace, but the urchin bites him and falls down, turning the grill's heat to very hot, without SpongeBob noticing. As SpongeBob cooks, he becomes increasingly hotter and sweatier. He notices his mistake too late and is shrunk down smaller than his spatula.
SpongeBob gets up and climbs onto the counter. He notes everything he sees to be huge. He then skates on the grill using butter, but the grill burns out and turns off. SpongeBob goes down to the bottom of the grill to investigate.
He finds the urchin in a mousetrap. He sets it free, and in return, it chases SpongeBob. The two run up and SpongeBob activates a soda machine. They then are washed into a drain, but SpongeBob is able to escape, while the urchin falls down.
Squidward then rings the bell for a Krabby Patty. He carries one out down into the seating area and thinks SpongeBob is an urchin trying to steal a Krabby Patty, them tries to smash it. Mr. Krabs picks SpongeBob and the patty up, and flicks SpongeBob to the Chum Bucket, mistaking him for Plankton. He lands on Plankton, who wonders why SpongeBob is so small, but then measures both him and SpongeBob and boasts about being taller than him. SpongeBob then lets some measuring tape wrap Plankton. He touches it, slicing Plankton into pieces.
SpongeBob is kicked out and lands on the Krusty Krab window. A kid picks him up, thinking he is an action figure. He shows the "action figure" to his friends and they fight over it. SpongeBob runs away, until he jumps into Squidward's shirt pocket. SpongeBob is now safe, and Mr. Krabs says the kids need to get their parents' money to get the "action figure." The kids run the customers out of the restaurant.
Mr. Krabs then realizes the "action figure" is SpongeBob after Squidward points out that they do not sell action figures. He then says that now that SpongeBob is so small, he only earns a penny a year. He is also now a personal hygienist. After doing stuff such as mowing a guy's back and doing something in another guy's toenails, SpongeBob takes a break and lays on the sink.
An angry Squidward uses SpongeBob to clean the dishes, mistaking him for soap. Squidward then drops SpongeBob into the soapy water, growing him so big that he takes up the entire Krusty Krab. Mr. Krabs, in SpongeBob's hand, yells for Squidward to call the fire department. The giant SpongeBob says there is no need for them to be called as he is on it, then walks there while using the restaurant as new clothes.

- This episode is available on the SpongeBob SquarePants Vol. 18 and The Complete Tenth Season DVDs.
- In the USA, this episode had made a promotion to the live-action Nickelodeon original movie Tiny Christmas, which premiered on the same day as this episode. The movie was part of Nickelodeon's 2017 holiday lineup. The movie is also the reason why they chose this episode to air that day.
- This episode was paired up with "Pat the Horse" during the original American airing, but has since been re-airing with "Sportz?"
- The title card is similar to that of "Fiasco!," only with different colors.
- Squidward says the Krusty Krab does not sell action figures, however in "Born Again Krabs," "Mermaid Man vs. SpongeBob," and "Yours, Mine and Mine" the kids' meal came with a toy, thus debunking his statement.
- The fourth wall is broken when Mr. Krabs thinks of how SpongeBob could be a personal hygienist, a sign appears in his thought bubble. He then grabs it and blows the bubble away from the screen.
- This episode marks the first usage of the track "Slide Whistle Stooges 2" since "Gary's New Toy."
- This is also the first time this track was used as title card music.
- This is the second episode in which someone shrunken is mistaken for an action figure. The first is "Mermaid Man and Barnacle Boy IV" when Squidward gets shrunken by SpongeBob and Patrick mistakes him for an action figure.
- In this episode, Ryan mistakes SpongeBob for an action figure.
- This is the third episode to involve shrinking. The first is "Mermaid Man and Barnacle Boy IV" and the second is "Squidtastic Voyage."
- This is the only season 10 episode to use the track "Jovial Pirate's Jig."
- This episode was the last season 10 episode in airing order.
- The episode's title is a reference to the film The Incredible Shrinking Man.
- SpongeBob makes a reference to Neil Armstrong's quote: "That's one small step for man, one giant leap for mankind."
- In the storyboard of this episode, Squidward starts sweating of being scared by the sea urchin. However, in the actual episode, he isn't sweating. This could be an error or it just never made it into the finished episode.
- When the little sea urchin turns the grill too hot, after SpongeBob tries to turn the grill less hot, it shows that it's not too hot, it only shows it's above too hot instead of too hot.
- The messy fish that says, "Personal hygiene service!" disappears in the next shot.
