Audio problem: In the beginning of "The Smoking Peanut", Spongebob takes his hat and spits it in the air like Clamu would do. Before he puts the hat in his mouth, he says, "a cannonball", the camera is on Spongebob and his mouth isn't saying that. He has his mouth open to put the hat in his mouth.
Continuity mistake: After SpongeBob confesses he threw the peanut at the oyster, a zoo keeper says, "wait, here is the real criminal", and he drags out Mr.Krabs. If you look at his pockets you can see food, candy, and other junk. Yet when the zoo keeper accidentally rips Mr.Krabs clothes off the pockets are completely empty.
Continuity mistake: When Sandy and SpongeBob are climbing the mountain at the beginning of "Pressure," when Sandy pushes the rocks down at SpongeBob, there were two big ones holding them that vanish. You could say that she pushed them down too, but remember that they were different colours than the smaller ones.
Continuity mistake: In The Smoking Peanut, after Spongebob sees Sandy he runs home. When he's trying to open the door if you look to the right the ground is completely flat and has nothing in it. Yet when Patrick comes, while he is saying, "I followed these footprints to this exact spot", there are footprints.
