Another one I remember that made me even more uncomfortable was I was a Teenage Gary due to how Squidward neglected Gary to the point of being pale and lethargic.

I wouldn't say I avoided it when it was on, but The Great Snail Race made me uncomfortable due to how Spongebob treated Gary.

One that I found when looking up on Google was The Black Cauldron

Honestly, I think it looks like too much at once

Welp, J's dead
