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
