How to Torture is a book that is only sold in Bikini Bottom, as the title says, it describes how to torture somebody. Squidward and SpongeBob SquarePants use it to torture Mr. Krabs because they think he is a robot. They torture him by tying him up in a chair and asking him questions. Every time he refused to answer a question, he was slapped. After that did not work, they used a psychological torture method by destroying all of his favorite possesions in front of him while he was still tied up.
