* I Was A Teenage Gary. The episode just feels... disturbing and dark, with Gary's neglect, the transformation, and the overall mood of the episode.
* Wormy. I was covinced that Wormy's true form WAS a monster and not just a regular butterfly, and that it ate Krabs and Squidward because they weren't seen in the episode again.
* MM&BB4's Squidward scene: This gross-out show comes in the middle of a perfectly innocent episode. Incinerated, skinned alive, bisected...
* Movie 1's Shell City, which gave me a phobia of dried sea animals that I still have.
* The face from Whobob Whatpants. So... uncanny.
* Plankton's Regular's very detailed flayings. Flaying is a very personal fear and ick of mine.
* One Coarse Meal. No more needs to be said.
* Patrick nearly BURNING GARY ALIVE WITH A FLAMETHROWER.
