Bubblestand / Ripped Pants - S1-E1

Character mistake: Ripped Pants: During the opening credits, Paul Tibbitt's name is misspelled as "Paul Tibibitt" (it is spelled correctly the second time it is shown), and Mark O'Hare's name is misspelled as "Mark O'hare." (00:11:54)

Hall Monitor / Jellyfish Jam - S1-E7

Continuity mistake: Hall Monitor: When SpongeBob sees the open window to the house, the window is opened to the left. When the two fish run out of the house after SpongeBob scares them, the window is opened the opposite way, then reverts back in the next shot. (00:05:19)

Atlantis SquarePantis - S5-E12

Revealing mistake: Atlantis SquarePantis: After the Atlantis van crashes through the museum's ceiling, Squidward is surprised that it's the magical path to Atlantis, and while Krabs says, "Nice hot rod flames," note how only the disembodied tip of Patrick's arm clips in front of SpongeBob's body (it even moves as Patrick moves), due to an animation error in this shot. (00:09:55)

Super Grover ★

Arrgh! / Rock Bottom - S1-E17

Other mistake: Rock Bottom: When SpongeBob sets up a cardboard version of himself and is shown sneaking to the bus, his holes are missing and he is perfectly square, instead of his usual sponge-like shape. (00:18:47)

Club SpongeBob / My Pretty Seahorse - S3-E12

Revealing mistake: In Club SpongeBob, when SpongeBob, Patrick and Squidward are in the forest, Squidward asks the magic conch shell if he can have something to eat. Straight after he asks "Can't you say anything else but 'No'?", it has a close-up of the shell. But Squidward's arm appears to be yellow, like SpongeBob's. This error was later corrected in 2019 when the episode was remastered for digital releases.

Arrgh! / Rock Bottom - S1-E17

Continuity mistake: Rock Bottom: When the cardboard version of Spongebob next to the candy machine is shown, it is frowning, but it turns into a smile when it falls over. (00:18:48)

Big Pink Loser / Bubble Buddy - S2-E3

Revealing mistake: Big Pink Loser: When Patrick says, "Why can't I do anything right?", and starts hitting his broom on the floor, the drinks that are supposed to be on the customers' tables are instead layered behind them. (00:05:18)

Big Pink Loser / Bubble Buddy - S2-E3

Revealing mistake: Big Pink Loser: When Patrick is answering phone calls, the third time he picks up and says, "No, this is Patrick", the anchor symbol on his hat briefly vanishes. (00:04:36)

Show generally

Revealing mistake: In "Patrick! The Game," when Squidward holds out the notepad, it's obviously written on. Just when the bubble transition comes, the notepad and all the other papers on the floor clear themselves.

Help Wanted / Reef Blowers / Tea at the Treedome - S1-E2

Continuity mistake: In "Help Wanted", the last time SpongeBob says "I'm ready!", his collar turns red.

Nikolai

Jellyfishing / Plankton! - S1-E3

Continuity mistake: In "Jellyfishing", Patrick and Spongebob slide down two ropes and burn their hands on them. The two shots after they land show them trying to cool down their hands and in the shot after that, the ropes they had just slid down on have disappeared.

Whatever Happened to SpongeBob? (WhoBob WhatPants) - S5-E18

Continuity mistake: Near the beginning, Spongebob picks up Gary, and some of his slime falls on the floor. When he hugs him and breaks his shell, the slime is gone. (00:01:56)

Have You Seen This Snail? - S4-E3

Revealing mistake: After SpongeBob tells Patrick, "I can't find Gary," text that reads "Rough Draft Korea" briefly appears on screen during the bubble transition. (00:08:24)

The Snowball Effect / One Krabs Trash - S3-E3

Other mistake: One Krab's Trash: When Mr. Krabs sticks the ghost drawing in Spongebob's window with the fishing rod, the shadow of the paper is visible on Spongebob, but there is no shadow of the fishing line holding it up. (00:17:27)

zenee

Bummer Vacation/Wigstruck - S4-E14

Other mistake: Bummer Vacation: When Spongebob says, "You're right, Gary. It is unhealthy to think of the Krusty Krab while I'm on vacation," his legs are missing. (00:05:55)

Trivia: In "Where's Gary?" when Spongebob takes the Dirty Bubble Challenge, look closely at the paddleball box; it has the Nickelodeon logo on it.

SpongeBob Meets the Strangler / Pranks a Lot - S3-E20

Continuity mistake: 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.
