Mrs. Poppy Puff is one of the main characters in SpongeBob SquarePants. Her occupation is to teach her students driving lessons at her boating school. SpongeBob has attended the school ever since its opening, and has failed his final driving exam countless times, often injuring Mrs. Puff and/or damaging the school in the process. Mrs. Puff hates teaching SpongeBob more than anything in her ocean world. SpongeBob SquarePants, Mrs. Puff's longest-standing student, is the bane of her existence. His distracting personality, reckless driving and inability to improve torment her to no end. SpongeBob has failed his driving test countless times, often sending Mrs. Puff to the hospital and causing immense property damage in the process. On multiple occasions, she has been sent to jail as a result of his actions. To make matters worse, SpongeBob has failed to come to terms with the reality that he cannot learn to drive properly, largely due to his boundless optimism. Due to this, she and Squidward Tentacles are on very good terms for good or evil, since SpongeBob is also Squidward's bane of existence, so she has someone to relate to. However, in comparison to Squidward, she is much kinder to SpongeBob (probably stemming from their teacher/student relationship); for example, while Squidward usually tells SpongeBob face-to-face that he hates him, Mrs. Puff has at least tried to hide her fury. Also, she has even acted nice to SpongeBob on some occasions, like in the episode Krusty Love, she showed no annoyance or anything negative to him, except when she screamed in horror when she thought they were doing the boating test, and the second time, when she's on her second date with Mr. Krabs, he states SpongeBob is helping him tonight, she says slightly worried, "Just a second. I need to go call my insurance agent".
