The Bully / Just One Bite - S2-E17
Continuity mistake: Just One Bite: When Squidward opens the door to the Patty Vault, the door opens to the left side. In the next shot, the door is not visible anymore, and when we see it again two shots later, it is now opened to the right side. A wheel also appears on the interior side of the door, which wasn't there before. (00:09:10)
