Tenacle-vision/I Heart Dancing - S7-E8
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.
Suggested correction: The audition could have been during the afternoon.
Jellyfish Hunters / The Fry Cook Games - S2-E16
Plot hole: As Spongebob is trying to let the Jellyfish out of their enclosure after discovering what Mr Krabs is doing to them, Krabs says, "That door will only open if I say...open." Then he suddenly realises what he's said and the door opens. How come the door didn't open when in his sentence he first said open? The door didn't activate itself until he said open the second time.
Suggested correction: Two likely explanations: 1. He said it more the 2nd time. 2. There was a delay.
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."
Continuity mistake: If you look carefully, you will notice that on the title sequence, patchy the pirate's eyepatch changes eyes. This varies from episode to episode.
Suggested correction: The eyepatch doesn't change position from episode to episode. You must be thinking of "Christmas Who?" where Patchy accidentally hits himself in the eye with his hook. And the pirate from the theme song's name is Painty the Pirate. Patchy and Painty are two completely different characters.
Help Wanted / Reef Blowers / Tea at the Treedome - S1-E2
Continuity mistake: In "Help Wanted" Gary doesn't have eyelashes. In every other episode he does.
Suggested correction: So Gary not having eyelashes could count as an early design for him. It's common that characters and environments may undergo changes after a pilot. Not a mistake.
But Gary never had eyelashes.
The Snowball Effect / One Krabs Trash - S3-E3
Continuity mistake: Throughout the episode "The Snowball Effect" Patrick's house is missing.
Suggested correction: I just watched this episode and on at least two occasions I could see Patrick's home in the background.
Help Wanted / Reef Blowers / Tea at the Treedome - S1-E2
Continuity mistake: The office door in the Krusty Krab is missing throughout the episode.
Suggested correction: It's a pilot episode. Things can change with a show when it gets picked up into a series.
Help Wanted / Reef Blowers / Tea at the Treedome - S1-E2
Character mistake: Everyone is carrying Sandy and Spongebob when Patrick's face completely disappears.
Suggested correction: I believe this is about the episode Wormy. However, it's already been submitted anyway.
