The Bully

"The Bully" is a SpongeBob SquarePants episode from Season 3. In this episode, Flats the Flounder joins SpongeBob's boating class.

Plot
In the beginning of the episode, SpongeBob is at boating school, and Mrs. Puff announces a new student will be joining the class. His name is Flats the Flounder, and he tells SpongeBob that he is going to "kick his butt." SpongeBob at first assumes him to be joking, but Flats soon makes it clear that he really means to beat up SpongeBob. An extremely paranoid SpongeBob tries to seek help and to reason with Flats, but to no avail.

SpongeBob asks Patrick for help, only to learn that he and Flats were buddies back in community college. He then tries to go to Mrs. Puff to help, who talks to Flats and explains to SpongeBob that "kicking his butt" means that Flats wants to become his friend, which is obviously not true. He then encounters Flats' dad in a boat and confronts him about his son's actions, only for the latter to go up to his father and threaten him as well. SpongeBob panics and sprints away.

He eventually runs away into town, where Flats attempts to run him over with a garbage truck, but he eventually drives over a banana peel SpongeBob drops, causing it to flip over. Flats awakens in the hospital, where he learns that SpongeBob saved his life by performing CPR on him for five hours straight.

Despite this, Flats continues to pursue SpongeBob; when SpongeBob runs through town, some people kick an old man's butt who they think is going to kick SpongeBob's butt. The old man was by a bus stop and Harold asks how many times they have to teach him this lesson. Eventually, he corners SpongeBob in his own home, where he proceeds to beat him up.

However, due to SpongeBob's spongy body, he absorbs the blows without harm. Flats continues to hit SpongeBob nonstop throughout all of next week, until he finally faints from exhaustion; his classmates cheer for SpongeBob. However, pitying Flats, SpongeBob starts a speech about how violence leads to nowhere, which ends with him making a fist. Mrs. Puff enters and sees Flats unconscious and SpongeBob making a fist, and believes SpongeBob beat up Flats. Mrs. Puff ends the episode by shouting to SpongeBob that she's going to kick his butt.
