The Bombastic Blathering of Brainy Blabulous is the ninth season 2 episode of The Epic Tales of Captain Underpants.
George and Harold head to a new school and find it to be the polar opposite of Jerome Horwitz Elementary. Things go downhill and that school's version of Mr. Meaner turns into villain Brainy Blabulous, the bizzaro version to The Frenzied Farts of Flabby Flabulous, as George said, calling Captain Underpants into action.
- Harold and George transfer schools finding Mr. Krupp, they find their friends with their names switched, only because the narrator mentions they got too lazy to create a whole new school and new characters, Erica has her first name and last name switched called Werica Ang, Gooch's name is said backwards called Choog, Dressy's name, like Erica's, is Kessy Drillman, Bo's name is Hwo Beemuth, and Jessica, Sophie One and Other Sophie have their names switched almost like Erica, Sessica and the Jophies namely Jophie One and Other Jophie.
- Harold thinks Erica's name Werica Ang has the first name and last name switched beginning consonant letter before the remaining vowel, as Piqua switched the "P" and "Q-U" between the "I' and the "A," naming it "Quipa."
- This is when George finds out that Erica Wang backwards is Gnaw Acire.
- This is the only Captain Underpants episode not to feature Gooch and Dressy, being replaced by Choog and Kessy.
- This is the only episode with Mr. Krupp being nice to the Harold and George. However, he becomes nice to them again in the later episode at summer camp The Shocking Showdown of the Staggering Sugamechanger. This makes sense as that Mr. Krupp as Captain Underpants is always nice to them even though he's the same man.
