Mya, much like Mr. Peterson, has light skin and green eyes. Though unlike her father, she has light-colored hair like her mother's. She also has a bird tattoo on the inside of her wrist. Mya died when her brother pushed her off the roof at the end of stage 5 in Hello Neighbor: Hide and Seek.


Hello Neighbor: Hide & Seek: Playing hide and seek with her brother while their mom is preparing breakfast. Then the parents leave, and the children continue their game. However, only her father comes home; he falls to the floor in tears and her mother’s bag in her hands. The mother of the children died. If Mya suffered this pain, then Aaron did not. While playing hide and seek, her brother Aaron accidentally threw her off the roof. Mya did not survive the fall.

Act 3: She can be seen in a photograph of her neighbor’s family in the family room, as well as her shoes.
