SpongeBob and Sandy are practicing karate against each other. After fighting in SpongeBob's house and at Barg'N-Mart, Sandy threatens SpongeBob with a drop of Volcano Sauce, and tells him that she will sneak up on him and fight him tomorrow. At the Krusty Krab the next day, SpongeBob thinks anyone or anything can be Sandy, so he is cautious and does not work much. When he strikes one of the customers, Mr. Krabs demands to know what is going on, so SpongeBob explains to him that he is doing karate.
Therefore, Mr. Krabs tells him to stop doing karate or he will have no choice but to fire him. Later, Sandy attacks him, and though SpongeBob attempts to explain Mr. Krabs' warning, Sandy does not believe or listen to him. At that moment, Mr. Krabs sees this and thinks he is doing karate with Sandy, so he ultimately tells SpongeBob that he is fired. This upsets SpongeBob and he starts throwing a big tantrum. Sandy quickly explains to him that SpongeBob tried to warn her, but she would not listen. Mr. Krabs gives SpongeBob his job back and tells him not to do any more karate, as he feels that it is poisoning his mind.
The two try to forget about karate and go to Seashell Park for a picnic. However, while slicing sandwiches, they begin doing karate against each other again.
After they destroy the park, Mr. Krabs catches them once more. SpongeBob admits the truth and explains that he cannot help himself. However, instead of firing SpongeBob, Mr. Krabs decides to have SpongeBob and Sandy slice the Krabby Patties with karate chops which makes twice as much money as before.

- In the scene where SpongeBob captures Sandy with the Novelty toy tongue, she has her left arm inside her suit while she guzzles down hot sauce. Once SpongeBob loops the tongue around her, her arm immediately appears outside of the suit.
