Deliberate "mistake": In karate choppers, when Spongebob slices the 'barnacle loaf' the piece flies into the air. As it falls past the mustard bottle, the mustard disappears. It's like the barnacle loaf erases the bottle.

Audio problem: In the scene where Spongebob is falling into Gary's dream, Spongebob is screaming for at least one second after he hits the ground.

Other: Sleepy Time: When everyone woke up SpongeBob near the end, Pearl is seen without her ponytail, but in the next shot, she has a nightcap on.

Continuity: In "Suds" after Spongebob crashes through his bedroom window, the blanket is hanging over the side and is all wavy, but when he's in bed it's completely plain and doesn't hang over the sides.

Continuity: When all of Spongebob's friends are formed around him, there's one scene where Pearl's hat disappears and then reappears, so for a few seconds she's completely bald. Her hair isn't even there.

Continuity: In "Sleepy Time" when the neighbours are crowded around Spongebob, Plankton is standing on the end of the bed. When the angle changes, he's gone. Then he jumps onto the bed before Patrick joins them.

Plot hole: When SpongeBob goes to Sandy's house, he blows a chocolate bubble with the shape of a heart. Sandy opens a little door and the heart comes in. But, if the heart enters, don't you think that water would have also entered?

Continuity: In "Valentine's Day", Patrick starts searching his present in the fair. Then he goes to a mountain and falls thinking that there will be his present. This mountain wasn't there before, even when they arrived to the fair.

Continuity: In "Valentine's Day", SpongeBob and Patrick arrive at the fair. They watch the fair. Patrick says "You bought me a fair?", and Patrick runs to the fair. When he starts saying, "Get out of my fair.", we see that SpongeBob is closer to the fair than he was before.

Continuity: In Valentine's Day, almost at the end, Patrick smashes some presents with his foot. After a while, Sandy arrives with Patrick's present (a chocolate globe), and you can see that the presents have dissapeared.

Audio problem: In the episode "Rock Bottom" when Spongebob says "Another funtastic day at glove world," near the beginning, if you watch Spongebob's mouth, it only says "Another funtastic." It never says "day at glove world."

Plot hole: When Spongebob gets on the bus he says he has no money, but later on in this episode he has money for the kelp machine.

Revealing: In "Rock Bottom" when Spongebob gets to the kelp bar and whenever he puts his hand in the bus vrooms, but watch when he runs over to catch the bus he runs right through the bus.

Continuity: In "Rock Bottom" when Spongebob is on line and the egg cracks, you can see the cracked pieces on the ground and then when he does his (in pants) "Barnacles, tartar sauce" you can't see the egg pieces.

Continuity: In the scene where Mr. Krabs is saying "this is no game" Spongebob is in his underwear, then it goes to Mr. Krabs and back to Spongebob and he's in his work clothes.

Continuity: In "Rock Bottom" when it shows SpongeBob with a glove on his nose, he looks out the window. In the next two scenes, it shows him again, but this time the little glove is gone.

Continuity: In "Neptune's Spatula", Patrick takes a picture of SpongeBob holding the spatula. When this happens, we can see that SpongeBob is a little worried because clouds have appeared there. However, after a while, Patrick shows the picture to Neptune, and we can see that in the picture SpongeBob is smiling and pointing with the spatula.

Continuity: When Spongebob grabs Squidward's legs you only see him grabbing at two of Squidward's legs and the other two legs have disappeared, but when the shot changes they're back again.

Continuity: Eventually after Spongebob takes the door wheel handle off, it comes back.

Deliberate "mistake": When Squidward is running to catch Spongebob, the people in the background and the foreground just repeat over and over (like the fish in the pink in the front is seen about three times) almost like it is a loop.
