SpongeBob walks over to Sandy's treedome to show her a new karate move. He arrives and sees her with someone else, which makes him think she is being attacked, so SpongeBob walks in to defend her, but gets stopped by the stranger's smelly feet. Sandy introduces SpongeBob to the stranger; Fuzzy Acorns, the greatest karate master ever. Sandy tells him that Fuzzy is here to see her karate skills. She is trying to earn a blacker belt, the highest belt in karate. SpongeBob wishes he had a belt, which Fuzzy overhears and tells SpongeBob that if he wants a belt, he has to earn it. He the proceeds into testing SpongeBob so that he can earn a belt. The sponge tries two tests that Fuzzy gives him, but he fails both of them. Now fed up, Fuzzy tells SpongeBob that he will face against Sandy tomorrow. If SpongeBob passes, he will receive a belt, otherwise, he gets nothing.
SpongeBob runs home to train himself overnight and then comes back, tired and unrested to spar with Sandy. He does very poorly, falls asleep, and is sad. Fuzzy said if he lasted longer, he would have rewarded SpongeBob with the clear belt, but says that SpongeBob is not even worthy enough to wear the belt that keeps his pants up, so he takes his belt and his pants fall. He also takes Sandy's black belt away for wasting his time with SpongeBob. He leaves and Sandy tries to talk Fuzzy into giving SpongeBob another chance, but Fuzzy never gives two chances and wishes to find food. Suddenly, Sandy gets an idea. She convinces Fuzzy to come to the Krusty Krab to see SpongeBob in action, so he goes (without an air helmet) to see him.
There, Squidward tells SpongeBob to stick with what he is good at and not try anything new. SpongeBob realizes he is right. Fuzzy watches, but he is still not impressed by SpongeBob's agility. He is only amazed when SpongeBob manages to slice Sandy's burger in twelfths with his hand. Fuzzy starts to think SpongeBob is more skilled than he thought, so he tries to attack SpongeBob, but SpongeBob is so busy that he does not notice Fuzzy sneaking up on him and dodges Fuzzy. Fuzzy decides he has had enough and tries to finish it, but SpongeBob bends over to get a dropped ketchup bottle, dodging Fuzzy's kick, sending him over to the door of the Krusty Krab. He looks terrible, but Sandy says Fuzzy just needs an air helmet. She gives him one, and he admits that SpongeBob is a worthy karate fighter, and so, he gives SpongeBob a black belt. As well, he gives Sandy his blacker belt for proving that SpongeBob does know karate. Without his belt, Fuzzy's pants fall down, revealing his underwear. The whole crowd cheers with laughter as the episode ends.
- When someone's belt is taken off, their pants fall down (apart from Sandy).

- Fuzzy's belt was originally gold, not black, and was changed for an unknown reason.
- Incidental 41 also appears in Sandy's treedome as a piano player.
- Fuzzy breaks the fourth wall by asking Sandy who she is talking to.
- In Bahasa Indonesia version, the episode simply ends with SpongeBob and Sandy thanking Fuzzy Acorns for giving them black belts as Fuzzy's underwear scene was cut due to underwear being considered vulgarity in Indonesia.
- The episode title references the film The Way of the Dragon, starring Bruce Lee.
- SpongeBob's training montage is a parody of the Rocky franchise.

- In the opening credits of the Russian dub, Doug Lawrence is credited as one of the writers instead of Derek Iversen.
- SpongeBob was actually complimented by Fuzzy when he said "a Kung Fu charlatan" because Kung Fu is actually stronger than karate.
