Other mistake: During the show's introduction in Seasons 1-8, when the kids chant "SpongeBob SquarePants!" for the second time, the whole screen shifts slightly to the left. As a result, when the lyric, "If nautical nonsense be something you wish" is sung, the far right side of the screen is slightly mirrored. Note how, when any of the four boats are at the right side of the screen, they are briefly duplicated. (00:00:16)
Other mistake: In "SpongeBob and the Clash of Triton," the title card says it is called "Neptune's Party," thus making it a wrong title.
Suggested correction: "Neptune's Party" was the original title for "The Clash of Triton."
Other mistake: Always in the older episodes (and sometimes in the newer ones), when a fish in the background takes his/her second bite of a sandwich, the sandwich still looks like the first mark. It does this on every bite after the first.
Jellyfishing / Plankton! - S1-E3
Other mistake: In "Jellyfishing", when SpongeBob and Patrick walk back to their houses covered in bandages, when SpongeBob says "Hey, Patrick." Patrick is mouthing what SpongeBob says.
Mermaid Man and Barnacle Boy / Pickles - S1-E6
Other mistake: In the end credits for the episode "Pickles", Bubble Bass is named "BubbleBass" (without a space).
Sandy's Rocket / Squeaky Boots - S1-E8
Other mistake: In the episode "Sandy's Rocket", Spongebob and Patrick go "alien-hunting." SpongeBob and Patrick are in Squidward's house. But when SpongeBob holds the hot water bottle, and he says "No, it's an egg-sack!", one of the drops leaking from the bottle goes up instead of down.
Nature Pants / Opposite Day - S1-E9
Other mistake: When SpongeBob throws the fire extinguisher at the grill, the patties are shifted to the left and appear to be floating.
MuscleBob BuffPants / Squidward, the Unfriendly Ghost - S1-E11
Other mistake: When Squidward is on the royal bed, Spongebob's Pineapple is nowhere in sight.
The Chaperone / Employee of the Month - S1-E12
Other mistake: When Pearl is crying in the Krusty Krab, the customers are just the same person over and over and over.
SB-129 / Karate Choppers - S1-E14
Other mistake: SB-129: When Squidward goes inside the freezer and shuts the door, the freezer's door handle vanishes mid-shot. (00:03:09)
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)
Mermaid Man and Barnacle Boy III / Squirrel Jokes - S2-E4
Other mistake: Squirrel Jokes: Near the end of SpongeBob's second act, he tells the crowd to give a big hand to Sandy, but to clap slowly, because she's a squirrel. Right as he says, "She's a squirrel," the holes on the bottom left of his face disappear mid-shot, then reappear. (00:20:09)
Mermaid Man and Barnacle Boy III / Squirrel Jokes - S2-E4
Other mistake: Squirrel Jokes: At the end of SpongeBob's second act, as he tells the crowd, "Thank you, you've been a wonderful audience," he opens his eyes briefly, and they are coloured yellow instead of white as they should be. (00:20:14)
Mermaid Man and Barnacle Boy III / Squirrel Jokes - S2-E4
Other mistake: Squirrel Jokes: When SpongeBob looks in the mirror backstage after finishing his second act, the holes on his face are not reversed in the reflection (one of the holes also vanishes and reappears mid-shot). The second time his reflection is shown, they are reversed. (00:20:18)
Other mistake: At the Krusty Krab, SpongeBob tells Squidward to write a letter. Patrick then tells SpongeBob that he ripped his paper, and SpongeBob's shoes lose their colour mid-shot. (00:06:45)
Other mistake: When Squidward opens the door to his house on Christmas morning, the door incorrectly overlaps the snow decoration on his house. (00:13:49)
Other mistake: When SpongeBob has his picture taken, his tie is missing.
Dying For Pie / Imitation Krabs - S2-E6
Other mistake: Dying for Pie: When SpongeBob seems to have exploded behind the brick wall, a brick flies out of the wall. Then, when the second explosion happens, the brick reappears in the wall mid-shot, then disappears when the wall hits the floor. (00:10:20)
Dying For Pie / Imitation Krabs - S2-E6
Other mistake: Dying for Pie: Near the end, Squidward tells SpongeBob that he spent the whole day with him doing all kinds of ridiculous things because he was supposed to explode. Right when Squidward says, "explode," a small portion of his head gets cut off briefly. (00:10:52)
Dying For Pie / Imitation Krabs - S2-E6
Other mistake: Dying for Pie: When SpongeBob trips on the rock at the end, he says, "Oops," before he even trips on it. (00:11:47)
