Failed a Spot Check: Mr. Krabs doesn't notice the destroyed Krusty Krab even when he walks into it, even "unlocking" the front doors with his key. He finally notices when he sits down in where his office used to be.
Gone Horribly Right: SpongeBob's plan to destroy the Krusty Krab to get his and Squidward's jobs back works, as they have to work there forever to pay off the damages.
Literal-Minded: SpongeBob takes Squidward's rally cry of "dismantling the oppressive establishment" too literally and destroys the Krusty Krab.
Squidward: That idea might just be crazy enough... to get us all killed!
Destructive Savior: Sandy and SpongeBob think they saved Bikini Bottom by sending the worm down a cliff. And they would have, had the town not been relocated to the bottom of that cliff.
It's Personal: Sandy goes after the worm because it ate her tail.
Moby Schtick: Like Ahab, Sandy hunts the worm for revenge. However, she is guided not so much by obsession as overconfidence, as she fails to heed SpongeBob's warnings that the worm might be more than she can handle.
Pride: Sandy suffers from this. She initially REFUSES to admit that SpongeBob was right about the Worm:
SpongeBob: Hey, wait a minute! I was right, wasn't I?!
SpongeBob: Ah, he IS too big for you, isn't he?
Sandy: Not now, SpongeBob!
SpongeBob: I want to hear you say it.
Sandy: Can we talk about this another time?!
SpongeBob: Say it!
SpongeBob:(sticks his foot out)Say it or I'll trip you!
Sandy:NO! Get away!
SpongeBob: Say it!
Sandy: NOT NOW!
Sandy:OKAY! You were right, and I was wrong! I was wrong-wrong-wrong-wrong-wrong! Are you happy now?!
SpongeBob:(with the smuggest look on his face) I knew it.
Justified, in that they probably should have been more concerned with the giant, carnivores worm chasing them! If anything, Spongebob was the proud one for not realizing that this was not the time for an apology.
Sanity Slippage: Old man Krabs doesn't take the idea of paying Sandy very well.
Mr. Krabs: NOOOOOOO!!! You'll never get a cent out of me! Never! (froths at the mouth) I'D RATHER THAT WORM COME IN HERE RIGHT NOW, AND EAT YOU ALL ALIIIIIIIIVE!!!
