"Squid Defense" is a SpongeBob SquarePants episode from season 9. In this episode, Squidward wants to learn karate from SpongeBob and Sandy, but he takes his new skills too far.



In the beginning of the episode, Squidward is working at the Krusty Krab, and SpongeBob accidentally karate chops him. Squidward asks what he is doing, and SpongeBob tells him that he is planning to do karate with Sandy, which Squidward thinks is stupid. That night, Squidward is grocery shopping and is approached by a large thug (The Creepy Creeper). Squidward assumes he is going to steal his groceries, so he runs to SpongeBob and asks to be taught karate. However, because SpongeBob is not very good at it himself, he is unable to teach Squidward.

Squidward injured.

They then go to Sandy for help. First, she makes Squidward promise not to use it for revenge and use it only for protection. Then, she and SpongeBob try to teach him, but cannot. When Squidward says that he had vengeance during training, Sandy then decides to quit on him, but Squidward says he would do anything, so Sandy makes him do all the work around the treedome, saying that it will teach him the basic movements. Finally, Squidward decides to quit. However, he accidentally flings acorns at himself that he is able to dodge. He then finds out that in doing all the work, he actually did learn karate.

So then, Sandy presents him his belt to show that he knows karate, but Squidward claims that he has "important business" to attend. He then finds the thug and uses karate to beat him up, with a lot of the moves being related to the housework he did around the treedome.

However, it turns out that he never wanted to steal his groceries; he wanted to return them. SpongeBob and Sandy then come to give Squidward his belt only to find out that he used karate for vengeance. Sandy says that Squidward does not deserve his belt, and SpongeBob scolds Squidward for not taking Sandy's advice. Then they walk away because Squidward dishonored their trust in him. However, Squidward has no shame of what he did and still considers himself as a karate master. Squidward is then arrested for assaulting the thug, as the episode ends.

Running gags

  • SpongeBob getting sliced in half and characters criticizing Squidward's body by saying, "What with the rubbery arms and the doughiness in the middle."
  • SpongeBob saying, "You missed a spot" when Squidward does Sandy's chores.
