Continuity mistake: On "One Krab's Trash", when Mr. Krabs draws a ghost on a sheet of paper, it shows before it goes into Spongebob's rooms that there's only writing on one side (i.e. the ghost) and when it goes into his room, a shopping list is on the back.
No Weenies Allowed / Squilliam Returns - S3-E6
Continuity mistake: In "No Weenies Allowed", the gatekeeper in front of the sailor club has a tattoo on his front with a heart and MOM on it. Sandy rips it out and places it back upside down. It now shows an upside down heart with WOW. In the next cuts between this and when Spongebob gets sent to the Weenie place, the tattoo suddenly has the heart downside up reading WOW, or upside down reading MOM. This is never possible because MOM was supposed to be with the downside up heart, not the upside down heart.
