Hooks are a fishing equipment object that first appear in the episode "Karate Choppers" and later play a major role in the episode "Hooky." They are known to be very harmful toward Bikini Bottomites and other sea creatures.
They are fish hooks used by fishermen and contain plastic fish attached to them that vary in appearance. The ones at Fish Hooks Park have cubed cheese attached to them to lure fish into going on them.
Role in series
A fish is seen using a fishing hook by constantly flinging it in and out of the water. The performance of this action reminds SpongeBob and Sandy of karate, a sport which they are prohibited from engaging in.
Later on, Patrick tells SpongeBob that the carnival has returned to town and encourages him to leave work to attend it. However, the so-called "carnival" is then revealed to be Fish Hooks Park, much to SpongeBob's horror.
Patrick indulges in the free cheese attached to the hooks and plays on them. SpongeBob tries to resist, but Patrick ultimately encourages him. Conforming to peer pressure, SpongeBob joins Patrick in playing on the hooks. They swiftly manage to avoid near-death experiences possible. Mr. Krabs eventually witnesses what the boys are doing and strictly prohibits them from the hooks or else consequences will follow.
The following day, Patrick breaks his promise and plans on playing in Fish Hooks Park again, encouraging SpongeBob to skip work and do the same. However, the latter refuses and keeps his promise. Upon walking to work, SpongeBob encounters a hook in the middle of the street and tries to resist, but subsequently gives up and plays on them once again.
The hook manages to be unremovable from his pants. SpongeBob then confronts Mr. Krabs about the hook and, with enough courage, admits that he was playing on them despite his warnings. As comeuppance, SpongeBob is forced to remove both his pants and his underwear and suffer the humiliation of public nudity.
Hooks play yet another prominent role in this episode. The movie that SpongeBob and Patrick go to see, Fisherman 4: Attack of the Hook, is a horror film about a fisherman reeling fish out of the ocean using a hook.
Later that night, Squidward tries to prank SpongeBob and Patrick by dressing up as the fisherman from the movie and threatening to turn them into fish sticks, scaring the pair with hooks.
The Fisherman uses a hook on SpongeBob with a fishing rod to get steal money from him, but he resists and ends up deep-frying him. SpongeBob ends up discovering that the Fisherman steals money from everyone every night as part of tradition.
