SpongeBob Meets the Strangler / Pranks a Lot - S3-E20
Revealing mistake: In "Spongebob Meets The Strangler" when that fish holds up Spongebob's dry cleaning at the supermarket, it looks like he is holding it up with a coathanger because his hand is up in the air, but you can easily see nothing is holding it up. It's just floating up in the air.
Suggested correction: The clothes are being held up by a coat hanger. It may be hard to see due to it blending in with the wall color, but if you look closely, it's there.
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)
Best Day Ever/The Gift of Gum - S4-E20
Revealing mistake: When Squidward says "I suppose if you haven't fixed my clarinet, the concert would have been a bust", Sandy's tail is the same color as her suit.
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)
Revealing mistake: In "Not Normal" when SpongeBob says "Hmm. This video tape should help," his left arm is missing. (00:01:25)
Revealing mistake: When Spongebob and Mr. Krabs are rolling in the pile of money, dollar bills are flying into the air. After crossing an invisible line, the dollar bills disappear in mid-air. (00:11:35)
