Mrs. Puff is SpongeBob's paranoid driving teacher and the owner of the town boating school, which is similar to a driver's education facility. She would like nothing more than to pass SpongeBob, as he is her most dedicated and hard-working student, but he routinely panics when he tries to drive a boat and fails every driving test he takes. His failures often result in crashes that lead to mass destruction and endanger Mrs. Puff. While she tries her best to be friendly and patient with her students, Mrs. Puff finds SpongeBob's unintentional recklessness exasperating. She is the long-standing love interest and girlfriend of Mr. Krabs.
