Wet Painters / Krusty Krab Training Video - S3-E9
Corrected entry: The training video says that the Krusty Krab closes at 6:00. But in every other episode, it closes at 8:00.
Bubblestand / Ripped Pants - S1-E1
Corrected entry: In "Ripped Pants" when Spongebob rips his pants off when he is singing the song and he only has on underpants and shoes, but the sleeves are still on, even though his shirt is off.
Mermaid Man and Barnacle Boy III / Squirrel Jokes - S2-E4
Corrected entry: In "Mermaid Man And Barnicle Boy 3" when Man-Ray puts on that metal arm, he puts a bomb thing on top of it. But when Spongebob and Patrick use the orb of confusion on themselves and Man-Ray points to the city right after Spongebob and Patrick crash the Invisible Boatmobile, the bomb thing is not on the metal hand anymore.
Born Again Krabs (aka A Penny Saved) / Safety Freak (aka I Had An Accident) - S3-E17
Corrected entry: In "Safety Freak," Spongebob breaks his butt. How is this possible, because in "The Bully," Spongebob is unable to be hurt by any force.
Krab Borg / Rock-a-Bye Bivalve - S3-E8
Corrected entry: In "Rock-A-Bye Bivalve" when Patrick says "Just call me daddy!" he raises his arms and he has a lot of armpit hair, but when he is watching T.V and raising his arms there is no armpit hair.
Texas / Walking Small - S1-E18
Corrected entry: In "Walking Small" when Spongebob gets a tan, in the next shot it's gone.
Correction: The tan is more of a visual joke and fits into the show's constant use of making a character look one way for a very brief albeit instant change before reverting back to how they originally looked. Examples include Patrick looking much fatter and with more armpit hair before returning to his normal weight and less armpit hair.
Corrected entry: In the episode "Pressure," Spongebob, Patrick, Mr. Krabs and Squidward go up to land and they can breathe air. But in other episodes like "Tea at the Treedome," Spongebob can't breathe air in the dome, or like "Big Pink Loser," where Patrick says, "Island, I got an award," but he can't breathe air for even a few seconds.
Correction: There is a few differences with the dome and when the gang was on the surface. The dome is somewhat like a glass house, sunlight is essentially the only element entering. That means there is either little to no moisture and no wind. Additionally the sunlight would make it much warmer than outside drying them out much quicker. With moisture in the air on the surface they would last longer. As we see they don't stay very long on the surface. As for when Patrick can't breath for very long in "Big Pink Loser" he was racing around everywhere and might have had to exert more energy jumping out of the water. In "Pressure" they were close to the surface before going on land.
Corrected entry: Whenever a license is seen, Spongebob mentions something about a mustache.
Correction: In the season 4, episode "Gone" he makes himself a licence and never says anything about a mustache.
Nasty Patty / The Idiot Box - S3-E4
Corrected entry: In Idiot Box, when Spongebob takes out the TV at the start, he's between his and Squidward's houses. He throws it across the road, and it lands in the trash can, but it's right in front of his house.
New Student Starfish / Clams - S3-E14
Corrected entry: In New Student Starfish, when Spongebob writes Patrick's name on the good noodle board, an empty space for Patrick's name suddenly appears.
Corrected entry: In the episode Dunces and Dragon's (Lost In time)., In the scene where SpongeBob gets a eyelash plucked out by a guard he has eyelash's but in every other scene he has no eyelash's just eyebrows.
Correction: Actually, spongebob always has eyelashes in every scene and episode.
Help Wanted / Reef Blowers / Tea at the Treedome - S1-E2
Corrected entry: When Sandy chopped the rock, the outside shattered and the inside disappeared.
Corrected entry: In the episode 3-21 "Pranks A Lot", SpongeBob asks what can he buy with 1 dollar, and the salesman gives him and invisible spray, that it's worth exactly 1 dollar. As we know, that's all the money that SpongeBob has, but when he pays the dollar for the spray, he gives more than 1 dollar.
Dying For Pie / Imitation Krabs - S2-E6
Corrected entry: SpongeBob marks the same item in his list twice when he does everything in his list with Squidward.
Correction: This is a joke to show how ridiculous the things on the list are. It is just one of the random things thrown in as a joke to see if you are paying attention.
The Great Snail Race / Mid-Life Crustacean - S3-E15
Corrected entry: How can there only be the three race contestants (Squidward, Spongebob, and Patrick)? Squidward surely wouldn't have spent his hard earned money just to con the other two into joining a race, so there should be more snails in the race. If Spongebob and Patrick had decided they didn't care about the race, would Squidward's snail have won by default, since there were no other racers?
As Seen on TV / Can You Spare a Dime? - S3-E5
Corrected entry: When Spongebob is making the krabby patties, the croud shout, "Onions! Cheese!" but Spongebob never put any cheese in the krabby patties.
Grandma's Kisses / Squidville - S2-E9
Corrected entry: In Grandma's kisses, Patrick is taking a nap. Then Spongebob has a fit about wishing he could be a baby again. But through the fit, Patrick doesn't appear for the rest of the episode. There is even a shot of the couch Patrick was sleeping on, empty.
Corrected entry: In various episodes the rooms in Spongebob's house change, and make it too big to all be the same size as the exterior of his house.
Corrected entry: The windows on Spongebob's house (other then the ones on the front) are always changing position.
Corrected entry: In several episodes, Squidward and Spongebob are cleaning plates and cups at the Krusty Krab - but you never see anyone eating/drinking out of one at the Krusty Krab.
Correction: The training video could have been outdated and cheapskate Krabs wouldn't have wanted to make a new one.
