At the Boat Management School, a new student is flounder Flats, who wants to beat SpongeBob. SpongeBob asks Mrs. Puff, Patrick, and Flats' father for help, but to no avail. As a result, Flats still starts hitting SpongeBob, but the blows do not cause him any harm, because he is a sponge. Flats beats Bob all day, and collapses from exhaustion. And Mrs. Puff, who entered the classroom, decided that Bob had beaten Flats.
P.S. Why is their toilet water so high?
