Factual error: Spongebob and Plankton are told to supervise the universe for Bubbles while he goes on a bathroom break, this result in Jupiter and Saturn colliding with each other. Saturn is depicted as much smaller in relation to Jupiter than it is in reality. Also, the effect of their collision is inaccurate since both planets are mainly made up of gas. (00:44:50)
Continuity mistake: When SpongeBob says he should sacrifice himself, the squidosaurs Rex has Mr. Krabs in his hands, but when SpongeBob walks to the counter, Mr. Krabs is right next to Squidward. When the camera zooms in on a group of citizens and Squidward, Mr. Krabs is gone. Then, another shot of the squidosaurs Rex, Mr. Krabs is in his hands again.
Continuity mistake: When Squidward scares the people off, some of the burgers they drop disappear and change position.
Continuity mistake: When SpongeBob and his crew are stranded on pelican island, Squidward releases a puddle of ink on the ground because he is nervous. When SpongeBob dabs the pen in the ink, in the next shot the ink is completely gone.
Continuity mistake: During the sequence of plankton about to steal the krabby patty formula, there's a ship in a bottle on Mr. Krabs desk. When SpongeBob arrives with a vacuum, it's gone.
Plot hole: Plankton replaces the secret formula with another message in a bottle, but later, when Spongebob catches him, he is replacing the bottles again.
Suggested correction: No, he is not. It might appear like he's about to do it due to the way Plankton and the bottles are similarly positioned as in the shot mentioned before, but there is nothing that indicates that he was about to repeat the same action. He had only picked up the bottle with the secret formula that he had pushed off from the pressure plate, he was then surprised to be caught by Spongebob so he accidentally knocked over the bottle he replaced the secret formula with. Also, when he accidentally knocked over the bottle, he didn't place the bottle he was holding on to back on top of the pressure plate to disable the alarm since it would mean returning the bottle with the secret formula back to its original spot.
Also, when it shows it when it happens about a few days or so ago, he doesn't knock it over.
Continuity mistake: Spongebob and Plankton are stuck between a large crowd. Some are facing their backs to the Chum Bucket, the others are facing their backs to the Krusty Krab. Later, the group facing their backs to the Krusty Krab disappears.
Continuity mistake: When Patrick is holding SpongeBob, he yells to the others that he has him. Two shots later, the background of SpongeBob, Patrick and plankton has changed - specifically, the pineapple house disappears.
