On a fine day at the Krusty Krab, Patrick is shown behind the restaurant climbing out of a dumpster eating a Krabby Patty. The camera then pans over to SpongeBob, showing him reading the "Krusty Krab Schedule" book, much to Squidward being annoyed. SpongeBob then claims that the book has a list of "his happiest memories". Squidward takes the book and "accidentally" drops it on the grill. However, SpongeBob has multiple copies of the book in a cabinet, which he proceeds to get one. SpongeBob then asks Squidward if he has a happiest memory, in which he replies, "No". Feeling concerned, SpongeBob tries to ask Squidward if he can help make a happiest memory for him, which he accepts. First, SpongeBob takes Squidward to a concert. That didn't go well, however, since the violin player accidentally shot Squidward in the eye with the violin. Then, both of them head to the Bikini Bottom Art Museum. One of Squidward's masterpieces is in the museum, which is praised by critics. Squidward is happy until a famous art critic named Fiasco burns his artwork with a flame thrower. And after that, SpongeBob takes Squidward on a hot air balloon ride. That doesn't go well, since Squidward is afraid of heights, so SpongeBob tries to get Squidward down by popping the balloon (because the balloon has no heater to make it deflate) and both of them land on a mountain which is actually Mount Bikini, ruining a mountain climber's chance to be the first one on the mountain. Then, the two along with the mountain climber slide off the mountain due to an avalanche. When SpongeBob and Squidward slide back to their homes, Squidward insists that he will never have a happiest memory. 2 weeks later, Squidward is left in his house doing nothing but being unhappy. SpongeBob then becomes even more concerned for Squidward and tries to get ahold of him, but fails. He then traps Squidward in a box, and takes him to the Krusty Krab, where he reveals that he created a party to cheer Squidward up. Unfortantley, SpongeBob failed to get anyone else to come, because some of them were busy or sick, so instead he made 100 paper-mâché life-sized models of himself. Squidward hates seeing more than one sculpture of SpongeBob in one place so he goes beserk and destroys all the paper-mâché sculptures and claims this to be his "happiest memory".
