Corrected entry: In the episode "Help Wanted" when Spongebob makes Krabby Patties for the anchovies, Spongebob chops lettuce, patties, and onions for some of the buns and the buns don't have patties, tomatoes, or cheese on them. When he's done dancing, when you look at the patty buns there is no onion, but there is a patty and lettuce. Also in later episodes, the way he made those patties isn't the way he makes them now. And the way he makes them now has tomatoes and cheese on them. But this could probably be wrong due to it being a pilot episode.
Corrected entry: When Patrick tells SpongeBob how to drive with the walkie-talkie, and SpongeBob starts driving with his help, you can see that in the track there's a wall of red bricks, that he must not crash. In order for not to crash it, SpongeBob must continue the road, turn left, turn right and turn right again. However, Patrick just says to continue the road, turn left and turn right. He didn't say about turning right again, and SpongeBob must have turned right to continue in the road. However, SpongeBob does continue in the road.
Corrected entry: In "Culture Shock," at the beginning of the talent show, Squidward says, "Welcome to the first annual Talent Show," which means they would have one once a year. However, at the end of the episode, Mr. Krabs says something like, "I can't wait till next week's show," meaning they would have one once a week.
