Continuity mistake: In "Selling Out", Mr. Krabs hears the footsteps of many customers approaching and the shot shows the entrance to the Krusty Krab from the inside, with no one in sight.

Enemy In-Law/Mermaidman and Barnacleboy VI: The Motion Picture - S4-E7

Patrick SmartPants/SquidBob TentaclePants - S4-E8
Continuity mistake: SquidBob TentaclePants: When the mixed-up SpongeBob and Squidward come out of Sandy's matter transporter, Squidward's arm is on the left, and SpongeBob's arm is on the right. Later on at the Krusty Krab, in the shot after Mr. Krabs tells both of them, "Alright, that's it!", we can see that both arms are SpongeBob's, when the left one is supposed to be Squidward's. (00:17:42)
Patrick SmartPants/SquidBob TentaclePants - S4-E8
Plot hole: In 'Patrick SmartPants' Patrick lost the top of his head after falling off a cliff, but Spongebob put it back on. Suddenly Patrick's intelligence skyrocketed, but wanted to return to his former self in the end of the episode. To do this he re-enacted his fall, but it was unsuccessful. They eventually figured out that Spongebob had in fact not put on Patrick's head, but a 'brain collar'. How did Patrick posses his memories throughout the 'intelligent phase' despite not having his own head (and brain)?
Patrick SmartPants/SquidBob TentaclePants - S4-E8
Continuity mistake: When SpongeBob and Squidward are combined, Squidward's arm is on the left and SpongeBob's arm is on the right, and that's how it is the whole time. Except in one shot, the shot of SpongeBob's head after Squidward says, "yellow freak." Look at the bottom and you'll see two SpongeBob arms, when the one on the left is supposed to be Squidward's.

Krusty Towers/Mrs. Puff, You're Fired - S4-E9
Continuity mistake: When the fish is at the front desk of the Krusty Towers, there is a silver bell on the desk. When Patrick arrives, there is no bell. Then Mr. Krabs puts Squidward in his place, and the bell is back, but has moved to the opposite side of the desk.

Ghost Host/Chimps Ahoy - S4-E10

Plot hole: In "Once Bitten", Mr. Krabs never unlocks the doors to the Krusty Krab, but at the end of the episode, Squidward enters with no problem.
Suggested correction: Maybe Squidward has a key to the Krusty Krab that Mr. Krabs doesn't know about.
He could still have a key, but we don't see it.
Whether or not Squidward owns a key to the Krusty Krab is beyond the point of the mistake here. The point is that Squidward is able to walk into the Krusty Krab despite the doors being locked, and he doesn't use a key or anything else to unlock them. He just pushes them open.
Maybe the doors were not locked properly.
Continuity mistake: In "Once Bitten", Mr. Krabs is holding a key, about to unlock the doors to the Krusty Krab, when a customer stops him. Two shots later, the key is missing from his hands.
Continuity mistake: In "Once Bitten", there is a keyhole on one of the doors to the Krusty Krab. Several shots later, the keyhole disappears.
