Role in series
Sandy and SpongeBob go to Seashell Park to get their minds off karate after making a promise with Mr. Krabs. While at it, the two have a picnic and decide to make Barnacle Loaf sandwiches. Despite having been prohibited from performing the sport, SpongeBob and Sandy furiously slice the ingredients into individual pieces in a rowdy way that is reminiscent of karate.
Mr. Krabs arrives at the scene to see that they were both performing karate despite his promise to fire SpongeBob if he performs it again. Admitting of his mistakes, SpongeBob accepts the consequences for his actions, but Mr. Krabs reconsiders and concocts the idea to have SpongeBob and Sandy karate-chop the food at the Krusty Krab as a faster profit booster.
The park appears when SpongeBob takes Squidward to it to greet everyone in town and introduce him to them and then do it again, but with Squidward wearing a salmon suit this time. SpongeBob introduces him to Incidental 42.
SpongeBob and Patrick are walking through the park, both constantly asking one another what they want to do today. After this, Patrick decides that he wants to buy a balloon, which they do, but they steal it from Lou's balloon stand without paying and deem it as "borrowing."
In the level "Sandwich Driving 101," SpongeBob and Patrick drive through the park in the Patty Wagon on their way to the edge of town.
In the level "Drive of the Knucklehead-McSpazitron," they drive back through it on their way to the Krusty Krab 2. During the latter level, Plankton has filled the park with statues of himself, oil wells, and bottles of Volcano Sauce.
During the montage of SpongeBob and Cuddle Eat Hugs playing, one of the places they play at is the park. There, Cuddle tickles SpongeBob, causing some Bikini Bottomites to look at him strangely when he laughs.
