Cornwallis Hankey is one of Mr. Hankey's children. He is presumed very smart, but he is conflicted with being a poo. He appears in the Season Four episode, "A Very Crappy Christmas" and South Park: The Stick of Truth.
Cornwallis is a talking piece of excrement with an orange and blue hat, glasses, gloves and an orange scarf.
Cornwallis is deeply conflicted by being a poo, he doesn't see the bigger picture. His father, Mr. Hankey, sings him a song about it but later reveals he only did so because he wanted to "stop his bitchin'".
- "A Very Crappy Christmas" - First appearance. Briefly loses his Christmas spirit until Mr. Hankey sings to him The Circle of Poo.
- "I'm a Little Bit Country" - Seen in the crowd of people along with the rest of his family.
He plays a minor role in Mr. Hankey's quests, you must rescue him from hobo's, who are using him for an entertainment "Shit Show" and return him to Mr. Hankey and Autumn.
- Cornwallis sings with the voice of ex-Temptation Louis Price in Circle of Poo, but with the high-pitched tones that Trey Parker gives to Mr Hankey when he sings Santa Claus is On His Way when on display to the hobos in the game.
