History YMMV / SpongeBobSquarePantsS1E13ScaredyPantsIWasATeenageGary

** When [=SpongeBob=] goes to Squidward's house after becoming a snail, is he doing so because he wants Squidward to be his owner, or is it because [=SpongeBob=] is trying to get Squidward to help him get back to normal?

** The spongesnail {{transformation|Horror}}.

* CatharsisFactor: Seeing the townsfolk be immensely terrified upon [[spoiler:the sight of Spongebob's exposed brain]] qualifies, given how they'd been scaring the bejesus out of him throughout the entire episode, with the likes of Squidward, Mr. Krabs, even [[JerkassBall Sandy]] included.

* AlternateCharacterInterpretation:

* TearJerker: When [=SpongeBob=] comes home to see that Gary is extremely sick, he bursts into tears and cradles the little snail in his arms. Definitely a case of AdultFear for pet owners.

* MemeticMutation: Comparing this episode, particularly the snail transformations, to what happens in the horror manga, ''Manga/{{Uzumaki}}''.

** Then there's Squidward's reaction when he sees [=SpongeBob=] after the fact; most of his panic is played unnervingly straight, only to end with him getting injected. The tense music playing during said scene doesn’t help.
** [[NightmareRetardant Negated at the end]] when Gary, [=SpongeBob=], and Squidward meow to the tune of "Yo, Ho, Blow The Man Down," annoying Patrick.

* CatharsisFactor: Seeing the townsfolk be immensely terrified upon [[spoiler:the sight of Spongebob's exposed brain]] qualifies, given how incredibly mean-spirited they'd been treating him throughout the entire episode, with the likes of Squidward, Mr. Krabs, even Sandy included.

* IdiotPlot: Squidward is given the simple task of feeding Gary once in the morning and once at night. He neglects to do this just so he can get a tan while [=SpongeBob=] and Patrick are gone. Then the veterinarian who comes in to help Gary leaves the task of injecting Gary with snail plasma up to [=SpongeBob=], since he's too squeamish to ''do his job''. [=SpongeBob=] has Squidward inject the snail plasma instead but keeps moving Gary out of the way because he feels Squidward is going to hurt Gary, causing [=SpongeBob=] to get injected with snail plasma instead. And it turns out that Gary just needed water to feel better. Acknowledged by Squidward himself after [=SpongeSnail=] breaks into his house:
--> '''Squidward''': [[CouldHaveAvoidedThisPlot None of this would be happening if I'd only fed that snail!]]

** Also the squeamish Doctor; was he being lazy, genuinely nervous, [[FridgeHorror or did he have some idea that the snail plasma, if misused, would cause a horrible mutation?]] All the above? You decide!
