The Polarizing Plight of the Pitless Poopetrators is the 39th episode of The Epic Tales of Captain Underpants and the season 3 finale.
The camp puts on a talent show after Cash Networth promises to buy it if the talent show is good. Though Melvin turns the performance into a real battle, Cash buys it at the last moment and saves George and Harold from Krupp.
- At the end, Harold and George claim that this episode is the series finale. But it isn't, as an airplane with a banner attached to it immediately flies by, saying there is more Captain Underpants content coming soon,
- At the end of the Toiletastics vs. Poopetrators play, the friends sing Dressy's song, ending in a "here," but for Jessica, she sings her way of saying "hair": "Har".
- Before Cash buys the camp and gets rid of Mr. Krupp, Mr. Krupp claims the boys need him and that he's "the balloon to George and Harold's air." Scenes from Season 3 appear, along with Mr. Krupp's song from The Ludicrous Lunacy of the Loopy Laserlightmare. This leads to George using the same quote from The Troublesome Treachery of the Thieving Toot Fairy, where the boys gave back Mr. Krupp's rule book before they got expelled.
- It is revealed that Bo Hweemuth not only can sculpt clay, as seen in his debut, The Costly Conundrum of the Calamitous Claylossus, but he can also sculpt ice.
- In the scene where Mr. Krupp tries to talk to Lee Dingman and then snaps his fingers to get his attention, he doesn't turn into Captain Underpants by accident like he did in the movie and in the later Halloween special.
- Smartsy Fartsy, Poopacabra, T.P. Mummy, Camoflush, and Clogneta return.
