When Patrick Star attempts to apply for a job at Shady Shoals Rest Home, Patrick is denied, because he did not have a diploma and/or a degree, because he did not finish high school. After receiving psychiatric therapy from Gary, Patrick decides that he wants to go back and finish high school. SpongeBob SquarePants warns Patrick of this decision and beseeches him to be cautious, as high school can be treacherous. Patrick then proceeds to the Bikini Bottom High School, where sea creatures such as Pearl Krabs, Judy, and Octavius Rex attend.
Meanwhile, at Goo Lagoon, Larry the Lobster faces a new threat to Bikini Bottoms community: Sharkdi. In an attempt to get rid of him, Larry threatens the stubborn Sharkdi to leave peacefully, before the BBPD comes and attacks. Sharkdi refuses and continues to terrorize the citizens of Bikini Bottom, so Larry takes matters into his own hands and threatens Sharkdi into a fight. Sharkdi agrees.Larry swings a roundhouse punch and Sharkdi staggers back when Larry's punch slammed into him. Larry felt his fist connect with Sharkdi's face. Larry paused, as he witnessed Sharkdi plummet to the sandy ground, while hearing a soft "oomph".
