Audio problem: When Bubble Bass runs out of the Krusty Krab he is gasping and panting, but his mouth stays closed, his mouth doesn't even open a centimeter.

Continuity: At the beginning of "Mermaid Man and Barnacle Boy", when SpongeBob and Patrick are watching TV viewing Mermaid Man and Barnacle Boy show, you can see that these heroes have 5 fingers on their hands, as the real human beings. However, when SpongeBob and Patrick meet these heroes, as in the rest of the show, you can see that now, the heroes, have 4 fingers on their hands, as cartoon characters usually have.

Continuity: Before Spongebob and Patrick takes their donuts, Patrick chooses one without chocolate. After a while we see it and now it's with chocolate.

Continuity: When SpongeBob asks Squidward to play his clarinet better,his night shirt is still on,but in the next scene it shows him again,but with his normal shirt.

Plot hole: In episode 1-7, Hall Monitor, Patrick says Spongebob is at the intersection of Conch and Coral, and we then see the street sign. However when we see Spongebob standing on the road, there is only one road, and no intersection.

Factual error: 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.

Other: Why is every single person in Bikini Bottom wide awake and living their normal lives in the dead of night? It's way past midnight and people are walking their pets and Mrs. Puff is in her school, grading papers. No school would be open that late.

Continuity: In "Squeaky Boots", Mr. Krabs starts hearing squeaky sounds everywhere. Then he goes mad, and says he took the boots from SpongeBob. In this point, notice of the restaurant floor's color. Mr.Krabs somehow lifts the whole restaurant but we can still see some floor (where Krab is). Notice that now the color of the floor has changed.

Continuity: When Pearl is opening her present the cake disappears.

Continuity: When Spongebob goes to answer his door, Patrick was obviously in front of the door. After Patrick says, "Spongebob doesn't like me anymore", it cuts to a different shot to show the outside of the front door, and Patrick has moved to the side of the door.

Revealing: In "Culture Shock" when Spongebob takes the green fish's order, he has a pencil tucked in his ear, but he doesn't have an ear, so it's just floating in thin air.

Continuity: When Spongebob is talking about Annoy Squidward Day, you see a calendar with 28 days, indicating that it's February, but the empty picture on the wall says January.

Plot hole: Spongebob says that this is the 27th award he has won, yet when he is standing in front of the pictures there are at least 30.

Continuity: A mistake that's complicated to say but I'll try. 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. This MIGHT count as both a continuity mistake and an audio problem, but I've submitted it using Continuity.

Continuity: When Spongebob is crying next to the employee of the month wall, (just before he says "How could I have let the quality of my work slip so much?") the order of the pictures is messed up. It goes December, February, January. Then, when we see the close-up of Squidward's face laughing, the order is correct again.

Continuity: When Spongebob, in his black suit and long legs, is at the door of Mr Krabs', he used a lever to lower himself down. When we cut back to Spongebob, it's gone.

Revealing: When Pearl is crying in the Krusty Krab, the customers are just the same person over and over and over.
