SpongeBob SquarePants (1999) - 188 mistakes in entire show

Other: There are times when Spongebob is right handed and other times when he's left handed. For instance, in the episode where he has to wear round pants, he fills out the Krusty Krab application with his right hand, but as he's taking notes from Squidward he's using his right hand.

Plot hole: 3-21: Spongebob Meets The Strangler / Pranks A Lot, in "Pranks A Lot", Patrick and SpongeBob scare Sandy. When Sandy runs, gets into her rocket and flies away. When she moved bubbles appeared meaning there's water in her tree house. There's no water in there in other episodes because she's a land animal and breathes air.

Continuity: In the episode "F.U.N", the chum bucket is not across the road from the Krusty Krab, but in every other episode it is.

Continuity: In "Pranks-A-Lot" when Sandy flies out of her dome in an escape pod to Texas, she leaves a big hole on top of her dome. In the next shot, it's gone. Very noticeable mistake.

Continuity: In "Where's Gary?" the length of the paddle ball string that SpongeBob uses seems to vary in certain shots. While the length is somewhat subjective one shot that is more conclusive is when Patrick finds Spongebob lying on the floor. The string on the paddle ball is fairly short. When the two get up to get a glass of milk, the string is now a lot longer.

Continuity: In the episode "Missing Identity", when Spongebob is talking to Patrick about saying "hi" to him the first time, Squidward's house is gone.

Plot hole: In the Mermaidman and Barnacle Boy episode with the shrink ray (Episode 3 or 4?) Plankton is shown as taller than the town at the end of the episode. However, when Spongebob is shrinking the people of Bikini Bottom, their sizes in the pickle jar seem to be equal with Plankton's actual height. In reality, Plankton should have been around the same size as the rest of Bikini Bottom's residence after the shrinking, not 5 times taller.

Continuity: Throughout the whole series there was never a tree in Squidward's front yard. But in episodes like Christmas Who and The Snowball Effect there is a tree in the middle of Spongebob and Squidward's houses.

Character mistake: In the episode when Spongebob and Patrick decide to make a Mermaidman and Barnacle Boy movie, Patrick states at one point that he had the cap on the lens of the camera the whole time. However, during the entire scene before he says this, you can easily see Patrick's camera, and the cap isn't on the camera.

Character mistake: In "I Heart Dancing", the lady at the Krusty Krab tells Spongebob the dancing audition is the next day. Later, Spongebob is practicing at Squidward's house for a whole night, and the next morning Squidward says they have one more day to practice, even though the audition should have been that day.

Other: In "Krabby Kronicle," when the two scientists exit Sandy's air dome, there are bubbles trailing behind them.

Continuity: In "Atlantis SquarePantis", when SpongeBob and Patrick are in the cave, the points on the amulet change size and shape between shots.

Continuity: 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. And 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.

Continuity: In "The Bully" SpongeBob accidentally runs into Flats' dad's car and there is only one seat. Later Flats is shown sitting in the car.

Continuity: In the Tattletale Strangler episode, the Tattletale's dots on his head change numbers constantly. Sometimes there are 5 on his right, sometimes 6, sometimes his left side has a scar and 5 dots, sometimes a scar and no dots.

Continuity: In "Spongebob Meets The Strangler" when The Strangler and Spongebob arrive at the pineapple, look at the door: there is no doormat below it, but a couple minutes later Spongebob pulls a key out from under the doormat that was not there before.

Other: In "SpongeBob and the Clash of Triton," the title card says it is called "Neptune's Party," thus making it a wrong title.

Continuity: At the start of "The Thing" the walkway to Patrick's house is missing.

Continuity: In "Not Normal" when SpongeBob says "Hmm. This video tape should help," his right arm is missing.

Factual error: Even though the show takes place in the ocean, there are separate bodies of water such as bathtubs. Whenever SpongeBob jumps into separate body of water, other than the ocean water he already lives in, he gets bloated like a regular sponge would. Wouldn't this mean he'd be bloated all the time?
