The Taxing Trauma of the Treacherous Tattle Trials Part 1 is the twelth season 2 episode of The Epic Tales of Captain Underpants.​


Melvinborg gets desperate for his younger self to get into his dream school, and has recreated George and Harold's schemes to do so, complete with nanobots for Melvin. It all goes downhill when the boys supercharge the nanobots and turn Melvin into Nanonerd.


  • Captain Underpants doesn't turn back into Mr. Krupp at the end, because the episode is not finished, this is part 1, and it's to be continued for The Taxing Trauma of the Treacherous Tattle Trials Part 2.
  • Captain Underpants wears a short white cape instead of his normal red cape.
  • Sophie One and Other Sophie's voices are heard when they're getting launched out of the dome by the Meanus Guy Trap and into the pizza place.
  • It is revealed that Mr. Krupp is allergic to confetti.
  • Many villains from Seasons 1 and 2 make an appearance, but it turns out there just holograms.
  • Jessica still blames Other Sophie for everything that's her fault no matter what even though she's not around.
  • The style of the Tatle Trials Dome makes reference to Lego Racers 2  final level ( Xalax´s Velodrome)
