Continuity mistake: In "Jellyfish jam", when SpongeBob shows the jellyfish to Squidward, and the jellyfish starts to do a lot of things, you see that Squidward is looking by his porthole in his house. The porthole is closed. However, when he says "How can anybody have fun with a jellyfish?" his arms go outside the porthole. But this is impossible, since the porthole is closed.
Audio problem: We see Spongebob in his long legs walk over to Mr. Krabs' house, then we see the door from inside the house. Through the window we see Spongebob's long legs, yet we hear him spring boing his way over when we see them already there.
Continuity mistake: In Squirrel Jokes, when Spongebob comes out for his second act, there's a back shot of a crowd, and there is one guy in the front right (from the back view) who is green. There is another front shot of the crowd and the guy completely disappears.
Continuity mistake: When Squidward has sort of a strict conversation with Spongebob, Mr. Krabs, and later Patrick, the 3 of them he was talking to, were side by side, but a shot later, Mr. Krabs and Spongebob are side by side, but farther from Patrick.
Audio problem: In "Pizza Delivery," when you see them being sucked towards the whirlpool (wide shot of whirlpool). Squidward says, "Let go of the pizza." several times before they actually get caught up in the whirlpool. But the time where he says the line and it automatically cuts to his face, when you see his face, it is the end of him saying the line so you hear, ".izza." You hear that, but when you see a close up of his face, his mouth is completely shut.
