Temmie Chang, also known as tuyoki, is the creator of Escaped Chasm. She has done sprites, animation, writing, and coding for the game.
Temmie appears dancing inside the Bonus Room, and provides the player answers to their questions. Additionally, the player can choose the option "You must be eliminated. Begone." Temmie will become confused, then disappear in a similar way to Zera.
She also appears in Escaped Chasm 2, the bonus game hidden in the Escaped Chasm's folder. She is shown dancing on a scrolling background of her face.
