A Taulipang myth (as cited in Eduardo Viveiros de Castro, “Immanence and Fear”):
“In the deep past, animals and people lacked an anus with which to defecate. I think they defecated through their mouths. Pu’iito, the anus, wandered around, slowly and cautiously, farting in the faces of animals and people, and then running away. So the animals said: ‘let’s grab Pu’iito, so we can divide him up between us!’ Many gathered and said: ‘we’ll pretend that we’re asleep! When he arrives, we’ll catch him!’ So that’s what they did. Pu’iito arrived and farted in the face of one of them. They ran after Pu’iito, but couldn’t catch him and were left trailing behind.
“The parrots Kuliwai and Kalika got close to Pu’iito. They ran and ran. Finally they caught him and tied him up. Then the others who had been left behind arrived: tapir, dear, curassow, Spix’s guan, piping guan, dove…They began to share him out. Tapir eagerly asked for a piece. The parrots cut a large piece and threw it to the other animals. Tapir immediately grabbed it. That’s why his anus is so huge.
“The parrot cut a small, appropriately-sized piece for himself. The deer received a smaller piece than tapir’s. The doves took a little piece. Toad arrived and asked them to give him a piece too. The parrots threw a piece in his direction, which stuck on his back: that’s why even today the toad’s anus is on his back.
“That was how we acquired our anuses. Were we without them today, we’d have to defecate through our mouths, or explode.”
