"The Lost Mattress" is a SpongeBob SquarePants episode from season four. In this episode, SpongeBob, Patrick and Squidward try to get back Mr. Krabs' lost mattress.



SpongeBob and Squidward arrive at the Krusty Krab, only to find out it hasn't opened yet. SpongeBob becomes saddened by this, until a very cranky Mr. Krabs comes after throwing out his back due to his old, lumpy mattress. SpongeBob suggests that he and Squidward buy him a new one, but because he does not want to waste his hard-earned money on his cheapskate boss, Squidward refuses, so Patrick joins SpongeBob in buying a new mattress instead. The two go to a massive mattress emporium, where they buy a comfortable new mattress and throw out his old one.

"How many do you think there are?" "Ten."

They make a card for him, which Squidward signs, giving himself full credit for the gift. The next night, the trio surprise Mr. Krabs with his new mattress. When they tell him that they threw away his old one, Mr. Krabs is furious, revealing that all of his money was in that mattress. He throws a tantrum at Squidward and asks him where the mattress was. Krabs then goes into a "Cash Coma," and ends up in the hospital, where the doctor explains that only the return of his money can save his life. Squidward insists that it was SpongeBob's fault, but a police officer shows him the card, which states that he is solely responsible. The cop says that if Krabs dies, Squidward will be charged for his death and sent to jail. Squidward begins to threaten to murder SpongeBob, but the police officer stops him. Squidward, SpongeBob, and Patrick go to the dump to retrieve the mattress, only to find that there is a vicious guard worm sleeping on top of it.

Meanwhile, the doctor realizes that Mr. Krabs has no insurance and cannot afford his hospital room, so he moves him into the hallway in front of the vending machines.

At the dump, Squidward tells SpongeBob and Patrick to go inside and get the mattress after warning them not to wake the worm, since it might attack. They climb the fence, but they end up becoming distracted by the view, causing an angry Squidward to shake and overturn the fence, accidentally trapping him inside with the worm who promptly mauls him, much to SpongeBob and Patrick's horror.

At the hospital, the doctors "surgically remove" Mr. Krabs from the building and leave him on the sidewalk to get to the "Nutty Nut Bar," a candy bar in the vending machines he is blocking.

Squidward then devises another plan, where SpongeBob and Patrick distract the worm while he retrieves the mattress. The worm becomes obedient to SpongeBob when he sees the wooden spoon he is holding up. SpongeBob unintentionally throws it towards Squidward for the worm to fetch, and Squidward is subsequently attacked by the worm once again.

Back at the hospital, Administrator Flotsam is outraged that Mr. Krabs has been left outside, and they push him down the hill. Next, Squidward has SpongeBob and Patrick dress as "choice cuts" so that the worm will eat them, telling them that they are in Halloween costumes and that when the worm sees them, he will realize that he forgot about Halloween and left to get candy (which is obviously false and meant for the worm to attack them instead of him).

SpongeBob and Patrick dressed as meats.

When Squidward expresses his certainty he will be not be hurt this time, Mr. Krabs suddenly rolls into the dump, running over Squidward, and lands on his old mattress, reviving him. He effortlessly throws the worm aside. Mr. Krabs notices SpongeBob and Patrick and growls at them, but they tell him it is them and Mr. Krabs asks why they are dressed as meat and SpongeBob tells him they're not just meat, but also choice cuts. Squidward gives up trying to get the worm to attack them and the worm then lands in Squidward's arms and begins chasing him out of the dump and down the road Mr. Krabs came from as the episode ends.
