An episode or moment that felt uncanny/liminal?

I like exploring when animated shows achieve this sort of feeling because you wouldn’t entirely expect it.

Episodes/moments I can think of off the top of my head: • SB-129 in its entirety • The ending of Spongehenge where Spongebob returns to the Krusty Krab after finally escaping the jellyfish • Spongebob and Patrick’s laughter echoing from underground while Squidward looks for them in That Sinking Feeling
