Continuity: Frankendoodle erases the door in SpongeBob's house (when they're fighting in the night). A few moments later you see the door is back.

Continuity: In "The Snowball Effect" when Patrick tries to make a snowball the third thing he makes is a DNA strand, if you look closely, when it is in closer, the DNA strand is shorter than when they go out on it.

Continuity: In "The Snowball Effect", sometimes Sqidward's doorknob is on the left, and sometimes it's on the right.

Continuity: In the scene where, Squidward accidentally squirts lemon juice in his eye it goes in his right eye but he squints with his left eye.

Continuity: When Mr. Krabs sees the headstone, it says SmittyWerbenManJensen and not SmittyWerbenYaegerManJensen.

Continuity: 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.
