|Mrs. Poppy Puff|
|Address:||Bikini Bottom, Mrs. Puff's House|
Mrs. Poppy Puff is one of the main characters in the series. She is SpongeBob's boating school teacher. SpongeBob "drives" her crazy. He is the only student in her class who has failed the exam so many times! She doesn't like talking about her husband, Mr. Puff, who unfortunately was turned into a lamp cover. Mr. Krabs has a crush on her and has gone on a couple of dates with her. She is voiced by Mary Jo Catlett.
Mrs. Puff is SpongeBob's favorite (and only) boating teacher. She is determined to keep teaching him no matter what. She lives in a pink house that was visited many times. She has been crushed and fell in love of Mr. Krabs. Mrs. Puff gives Mr. Krabs lots of money. In the episode Krusty Love she gives him three bills and in The SpongeBob SquarePants Movie, she paid $9.00 to see the ceremony of the Krusty Krab 2.
She owns Mrs. Puff's Boating School. In "Boating School," SpongeBob failed only 39 times. In "No Free Rides," SpongeBob had failed an entire trimester of destroying Bikini Bottom. In "Driven To Tears," SpongeBob flunked 58 times. In the episode, "Mrs. Puff, You're Fired," SpongeBob flunked more than 1,258,058 times. SpongeBob only gets F- on all of his driving exams except when Sergent Roderick the shark comes and improves his skill only a little bit. In "Boat Smarts," Mrs. Puff shows a video how to be a good driver with SpongeBob as the bad one, and Squidward as the good one.
Mrs. Puff is also famous for her puffing up. In few times when SpongeBob hits something, Mrs. Puff pops out like a really big pufferfish and talks in a very deep manly voice for example "Oh SpongeBob, why??". Poor Mrs. Puff is also forced to receive complaining and bad attitude yelling from Fred, who is famous for yelling and complaining "My legs!” She also has been part of Squidward's Band in Band Geeks. Poppy Puff has also been doomed to stay with SpongeBob for another whole year; Mrs. Puff decides to give him extra credit.
Mrs. Puff has a snail that looks just like Snellie. However, the snail is not Snellie. The snail was raised by Mrs. Puff since she was a little girl, and then the snail was stuck on top of a tree. SpongeBob rescued him as in The Sponge Who Could Fly. However, the snail is never mentioned again like Snellie. Squidward must not know about that snail.
She also wants to be a water-color artist, as seen in Mrs.Puff, You're Fired, despite the fact that she lives underwater, which means only crayons and markers are available to draw with rather than paint or watercolor underwater. She can draw pictures very real, and she can draw really fast.
In Pet or Pests, she is freaked out by looking at the baby worms that SpongeBob is offering. Mrs. Puff hates Mondays.
Mrs. Puff has yellow hair. She wears a red shirt with a yellow string tie, a blue shirt with a collar, a red skirt, and some magenta boots. She also is large, but she's not fat or overweight. It's just that she's a pufferfish, but when she blows she expands. Usually, she often wears prisoner clothes because she goes to jail often. She also has teal fins. Mrs. Puff can also be seen in 2017 videos sent by Pamtri, a computer animation group. A noteable video example is Mrs. Puff has has enough.
 Jailtime and Crime
Mrs. Puff has gone to Bikini Bottom Jail more than fifteen times in the series. Some notable occasions include:
- In Hall Monitor, when SpongeBob almost destroyed Bikini Bottom, she was sentenced to jail for at least 6 months.
- In Doing Time, when SpongeBob almost destroyed the city again, she went to jail for a long time.
- In No Free Rides, she'd have to spend another year with SpongeBob SquarePants, so she stole SpongeBob's new car. Then, she got arrested for crashing it into a Police Car. But the warden agrees to release her if she will give free boating lessons.
- In Ditchin, she goes back to jail and sentenced for one week for ditching jury duty.
 Mrs. Puff's Boating SchoolMain Article: Mrs. Puff's Boating School
Mrs. Puff's Boating School has only one classroom, despite a goof where SpongeBob tells Mrs. Puff if he can be in a different class in the episode: The Bully. Mrs. Puff's classroom had at least 3 entrances, but all of them were broken when Sergeant Roderick literally threw 3 students through the doors without opening them. Mrs. Puff usually teaches about boating and driving and then let the students pass the exam. The school has many rules, and many students in its time. SpongeBob is the longest known student, but many other people such as Patrick and Flats the Flounder have attended.
