SpongeBob and Sandy are at Goo Lagoon. They were about to go swimming in the lake but Sandy points out that SpongeBob is not wearing his swimsuit, so SpongeBob goes into the clothing tent to change. While SpongeBob is in the changing room, he puts on his Karate suit, wanting to surprise Sandy. However, when he comes out of the Changing Room and surprise attacks Sandy, Sandy slashes him, showing she had the same idea. During the battle Sandy hits SpongeBob so hard he goes flying out of the water. Sandy uses this time to get ice cream. When SpongeBob flies back into the water, Sandy pauses her ice cream moment to hit SpongeBob and he goes flying. SpongeBob flies so far he ends up at a place with a group of strong men waiting in line for something. SpongeBob flies into one of the scary men, and he gets angry, thinking it's a piece of paper. He turns around to see who threw the "Paper" at him and SpongeBob gets scared because the man is mean and tough. SpongeBob covers it up by hiding until Sandy comes and he comes out. Sandy comes and asks what they're standing in line for and the man says they are waiting in line for The Salty Spitoon, the toughest sailor club in Bikini Bottom, and that only the toughest fish can get in.
The bouncer, Reg allows Sandy in as she's one of the toughest fighters in Bikini Bottom, but rejects SpongeBob because he is not tough enough. Reg suggests that SpongeBob should instead go to Weenie Hut Jr. and then Super Weenie Hut Juniors, much to SpongeBob's intense annoyance and humiliation. SpongeBob tries other methods, like telling him a story about how he stubbed his toe while watering his spice garden and only crying for 20 minutes, and wearing a wig to disguise himself (A sponge called Drifter is also shown and mistaken for SpongeBob, but the real SpongeBob shows up with a clown wig and Reg lets the Drifter in).
Finally, SpongeBob goes to Weenie Hut Jr. The patrons talk about special days at Weenie Hut Jr. and the Animatronic Server calls SpongeBob a weenie, annoying him. The patrons then suggest ways for SpongeBob to prove his toughness and gain entrance. SpongeBob figures that the quickest way to do so would be to win a fight, but since he is not very strong, he decides to stage a fight with Patrick. The fight with Patrick is supposed to be Patrick letting him win. They sling insults at each other to make the fight seem more realistic, but SpongeBob calls Patrick "Tubby," causing him to get angry and attack him. SpongeBob reminds him that he's supposed to let him win and Patrick proceeds to beat himself up as if there were an invisible person attacking him, even flinging himself into the lake. Reg becomes amazed about SpongeBob beating up Patrick without touching him and finally allows him to enter The Salty Spitoon.
SpongeBob runs inside the club, but he slips on an ice cube and falls, putting him in the hospital. He initially is admitted to Bikini Bottom General Hospital, but while talking to the doctor, he refers to his injuries as "boo-boos." The doctor suggests that SpongeBob is admitted to "Weenie Hut General," much to his dismay.
In the partner episode, "Squilliam Returns," one of the sheets that get shredded when SpongeBob clears his mind is titled, "Spice Garden Tips." What makes this interesting is that SpongeBob mentions his spice garden in this episode.
