The Frenzied Farts of Flabby Flabulous is the first episode of the first season of The Epic Tales of Captain Underpants, was premiered on Netflix on July 13, 2018.


A goof-off in gym class costs George and Harold when an angry Mr. Meaner finds out that their latest comic book insults him, and an accident involving his butt and Melvin's new machine turns him into their newest villain.


  • This is the only episode to feature a Flip-O-Rama segment.
  • This is the first episode featuring debuts of Harold, George, Erica, Jessica, Captain Underpants, Mr. Krupp, Mr. Meaner, Sophie One, Other Sophie, and Melvin.
  • Mr. Krupp mistakes "you're innocent until proven guilty" with "you're guilty until proven innocent" at the beginning of Chapter 3, when George and Harold are in his office.
  • George says Harold's elephant sick joke doesn't make sense. However, Harold most likely used elephant for the word faint.
  • At the begining, before the intro, the words 'off' are the only red letters on the sign, but 'p' and 'e' can be found on the ground, with no other 'f' in sight. You're welcome for telling you this!
