Corrected entry: Squidward spray painted "loser" pointing to his own face (which he also spray painted) on one of the front doors of the Krusty Krab. When Spongebob first goes into the Krusty Krab, the drawings (or whatever they were) disappear.
Corrected entry: In "Your Shoe's Untied," Spongebob comes into the Krusty Krab and says "I can't let Patrick see that I still haven't tied my shoes." Patrick and other customers are eating. But Spongebob is the only Krusty Krab frycook, so how could they be eating if he wasn't there.
Corrected entry: In "Pre-Hibernation Week," when they're swimming in the ice-cold water, Sandy says she has three days left until hibernation. But then, Patrick comes home with groceries and asks, "Who are you people?" to everyone under his rock, indicating that Spongebob had only been under the rock while he was on a daily errand. So it had only been a few hours since Sandy said she had three days left, but yet she starts hibernating.
Corrected entry: In "I Had An Accident", there's one scene where Sandy sticks her head into Spongebob's porthole to yell at him. The porthole is NOT open, therefore Sandy would've hit her head in the porthole window.
Corrected entry: In "Pickles," Spongebob is confused about everything and when he has to sleep, he says, "So is it mattress, mattress, blanket, pillow, Spongebob? No, that's not it..." and every time he tries to figure out the order he names two mattresses. But Spongebob's bed has three mattresses.
