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 towards the Bikini Bottomites.
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, and are likely used 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 doing or else SpongeBob will lose his job.
At the Krusty Krab, Mr. Krabs warns everyone that the hooks have returned to Bikini Bottom. After finishing his speech, he strongly urges everyone to stay away from them.
Patrick then tells SpongeBob that the carnival has returned to town and encourages him to take a break from work to see it. However, the so-called "carnival" is then revealed to be Fish Hooks Park, much to SpongeBob's concern.
Patrick indulges in the free cheese attached to the hooks and plays on them. SpongeBob tries to resist, but Patrick only encourages him. Conforming to peer pressure, SpongeBob eventually joins Patrick in playing on the hooks and the pair then proceeds to jump off after reaching their destined height, to the fishermen's disappointment.
Playing on the hooks with Patrick causes SpongeBob to miss his a majority of his job. Amongst witnessing him and Patrick playing on the hooks, Mr. Krabs warns them about doing so and strictly recommends that they do the "sailor's promise" not to do it again, which they 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 eventually gives up and plays on them once again.
The hook manages to be unremovable from his pants. Attempting to hide it, SpongeBob confronts Mr. Krabs about the hook and eventually admits that he was playing on them despite several warnings not to. As a result, the only solution to recovery is removing his pants, which SpongeBob reluctantly does. However, the hook has got SpongeBob's underwear as well, and he is required to take them off too, which he refuses to do and is about to be reeled in by fishermen. To prevent his death, he grabs onto the Krusty Krab's clam sign as a means to remove the hook from his underpants, which results in them being ripped off and his naked body crashing into the Krusty Krab's doors, to the laughter of Pearl and her friends.
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.
