"Mom" is the mother of the Protagonist. Her name and identity is currently unknown.
During gameplay, the protagonist can knock on her bedroom door, even though she never answers. Knocking on Mom's door during a hide-and-seek game will trigger Mama Tattletail's jumpscare.
However, if the protagonist attempts to knock on Mom's door during the beginning of the third round of hide-and-seek, the door will actually open and Mama will be seen inside. She will jumpscare the player immediately afterwards, however. If the protagonist waits until the yellow Baby Talking Tattletail starts speaking before they open the door, they will be able to enter the room. Mama Tattletail will be seen for a split second but then vanishes. Two seconds after entering the room, Mama will jumpscare the player. There is currently no way to prevent her jumpscare upon entering Mom's room.
