Flatts the Flounder

''This is A Character from Spongebob Squarepants. For Natt, See Natt (Disambugation)''

Flatts Monroe Flounder is a flounder who first appears as a cameo in "Sandy's Rocket", where he was one of SpongeBob's "alien hunting" victims. He also makes another minor appearance in "Texas", where he attended Sandy's Texas party. His only major appearance, however was in "The Bully", he joins Mrs. Puff's boating school and wants to "kick SpongeBob's butt." Spongebob takes this extremely seriously, reacting as if he were going to actually kill him. He makes many attempts to reason with and/or escape him, but to no avail. He even calls Patrick to protect him, only to find out that Flatts is with him and that they were community college buddies. He also tries to go to Mrs. Puff to help, who talks to Flatts (much to Spongebob's dismay) and explains to Spongebob that "kicking his butt" means that Flatts wants to become his friend (this is obviously not true). Flatts goes so far as to chase Spongebob out of school into town, even trying to run him over with a garbage truck. However, the garbage truck slips on a banana peel and flips over, critically injuring Flatts. He wakes up in the hospital and learns that Spongebob saved his life through CPR, yet he STILL wants to kick his butt. Eventually, Flatts corners Spongebob in his own home, and proceeds to "kick his butt" by repeatedly hitting him. However, Spongebob discovers that his spongy body simply absorbs the blows and does not hurt him at all. Flatts continues to hit Spongebob throughout the whole week until he finally passes out from exhaustion one morning at boating school.

Flatts' body is shown to be somewhat two-dimensional, hence his name.

He has a father, who Spongebob attempts to convince to stop him, but he appears to live in fear of his own son.
