Corrected entry: In "Suds", we see that there's a mountain at the back of the Krusty Krab. I think it's obvious that the mountain isn't in any other episodes of the show.
Corrected entry: At the end, everybody is at SpongeBob's house telling him not to be in their dreams anymore. Pearl is also there, angry. But SpongeBob didn't do anything wrong at Pearl's dream.
Correction: Pearl isn't angry with Spongebob for ruining her dream. She's angry because Spongebob just popped in and disturbed her dream, only for him to leave immediately saying he was looking for Mr. Krabs' dream.
Correction: The mountain is added for comedic value and many other landmarks in Spongebob change simply for the same reason. However in another episode, Spongebob races Sandy down the hill and the hill is behind the Krusty Krab.
