Krabby Land / The Camping Episode - S3-E19
Corrected entry: In "Krabby Land" SpongeBob arrives at the Krusty Krab, dressed like a flower, saying about the spring meaning, and so on. Later, when SpongeBob and Krabs know that there's a new park for children, Krabs says he has an idea and goes away. The next scene shows SpongeBob saying something like "What could happen with Mr. Krabs yesterday?" He says "yesterday", meaning that the scene with Mr. Krabs and the Krusty Krab was the day before. At the end of the episode, SpongeBob says "I thought I knew the spring meaning, but that was long ago." Squidward says "Wasn't that this morning?" But that was the day before, when SpongeBob arrives saying about the spring meaning dressed like a flower, not that day.
Correction: Squidward really doesn't like Spongebob. When he said, "wasn't that this morning?" he was being sarcastic and saying that Spongebob is basically stupid for changing his ideas so fast.
