SpongeBob begins singing while cooking the patties. An annoyed Squidward tells him about real music and plays his clarinet, causing the customers to run away from the Krusty Krab. After being told to stop by Mr. Krabs, Squidward goes outside and throws a tantrum, complaining that no one appreciates music. Plankton, watching from the Chum Bucket, believes that Squidward may be the key to the formula.
Later, Plankton tries talking to Squidward, but he fails to. Then, he makes several attempts to trick Squidward, among these were pretending to be a girl scout and pretending to be one of Squidward's species, all resulting in Plankton getting the door literally slammed in his face. SpongeBob tells Plankton that he might gain Squidward's friendship if he compliments him on his music. Plankton later meets with Squidward and persuades him to play his clarinet. At first, Plankton is tormented by the awful clarinet music but then wears Professional Grade Earplugs to block the noise and pretends to like the music. Squidward marches across Bikini Bottom, playing his clarinet, and Plankton follows along, while everyone else is tormented by the noise. Plankton also sings a song about Squidward's clarinet music as Squidward plays bad notes on his clarinet.
This friendship, however, wouldn't last as Plankton tells Squidward about the secret formula. Squidward tells Plankton that despite 20 years of working, he had never seen the making of a Krabby Patty. Squidward tells Plankton that his music is getting better and plays his clarinet, making windows and mirrors across Bikini Bottom crack and break. Squidward then says that he is going to quit his job and become a full-time musician. Plankton gets so angry that his earplugs come off, and he is once again tortured by the noise. Plankton steals the clarinet, causing Squidward and SpongeBob to chase after him. Plankton is shortly confronted by the police about a "bad music" crime and is arrested for being the only one to hold the clarinet. As he is driven away, the police car runs over Squidward's clarinet. After SpongeBob retrieves the broken clarinet, Squidward once again "hates people."

Also, in the Season 9 episode "Goodbye, Krabby Patty?" (which was set in January 2016), Squidward states that he has been working at the Krusty Krab for 17 years (which would place the year he was hired to at least 1999, which is also the year that the series premiered).
When the clarinet was run over, it resembles the shape of a bass clarinet.
Squidward says he's never seen a Krabby Patty being made before, but in "Employee of the Month," he is seen making a gigantic mountain of Krabby Patties, along with SpongeBob.

When Plankton yells at Squidward and mentions that Squidward has worked at the Krusty Krab for 20 years, he says the Krabby Patty is "the only thing on the menu".

When Squidward and Plankton first got to Goo Lagoon, Plankton was much larger than usual, but then back to normal height in the next scene.
