3 The Lost Mattress

Mr. Krabs is having trouble sleeping on his old mattress, so Patrick and SpongeBob buy him a new one and Squidward takes the credit. Unbeknownst to them, Mr. Krabs' money was in the mattress because he doesn't trust banks. Mr. Krabs ends up in the hospital suffering from a "cash coma", leaving SpongeBob, Patrick, and Squidward to retrieve it from the nearby dump; and Squidward will go to jail if Krabs doesn't come out. After a few encounters with a guard worm, they retrieve the mattress and Mr. Krabs is awakened from his coma.
