This is oddly specific, but I'm going to lay out the steps to get this.
-
Play a game with any tribe skin that changes its animals (I believe they all do)
-
Other tribe must be the ∑∫ỹriȱŋ Midnight skin, but may also work with regular ∑∫ỹriȱŋ
-
The tribe skin (I've brought proof of Ai-Mo and Yădakk) must get Mind Benders
-
The ∑∫ỹriȱŋ has to spawn a Demon from a grave that was the other tribe’s animal before it got into the ∑∫ỹriȱŋ borders
-
The other tribe must mind bend that Demon, and it will become the tribe's original animal before the tribe skin was introduced, but keep the body/clothing of the tribe skin
