"I'm floor shadowing"- Mr. Ree
The Shadowy Syndrome of the Sinister Splotch is the sixth season 2 episode of The Epic Tales of Captain Underpants.
Just as George and Harold are preparing for Robe-i-con, horror is at their doorstep when it seems like Captain Underpants is robbing banks. Eventually, they find out an evil robe named Splotch from a previous encounter had taken over Mr. Ree's body and is framing the waistband warrior to avoid any bumps in his scheme, and he now plans on controlling all robe-wearers on earth to help in world domination.
- The robe from The Jarring Jerkiness of Judge J.O.R.T.S. returns in this episode.
- This is the second episode where Captain Underpants doesn't turn back into Mr. Krupp at the end. Captain Underpants is present for the episode leaving Mr. Krupp not returning except the beginning even though Harold and George were almost going to.
- This acts as a sequel to The Jarring Jerkiness of Judge J.O.R.T.S. Because the rope Jerry found is back...
- Splotch is the only villain who wasn't created by accident, unlike past villains.
- The line "There can be only one!" is a reference to Highlander, as Mr. Ree and Splotch 's voice actor, Clancy Brown, starred in that movie.
- Harold and George repeat saying "no" so many times thinking that Captain Underpants is the one robbing banks, but then say "yes" only once after that and just before the theme song.
- The Melvins' tailor's name "Giuseppie" makes a return in The Problematic Pandemonium of the Punishing Plungerina.
- Moral: You're innocent until proven guilty. (even though Mr. Krupp spoils that for the boys in The Frenzied Farts of Flabby Flabulous, after Mr. Krupp says the boys can go milk goats if they hit 500 office visits.
