Template:Infobox characterThe Protagonist is the unseen main character of Tattletail. They are the child that the player controls. The Protagonist gets a Tattletail for Christmas and opens it five days early, facing the consequences.
Not much is known about The Protagonist's appearance, but it is assumed they are a child no older than around ten. It can be presumed that they are deceased after their encounter with Mama in the game's normal ending; however, if the player unlocks the secret ending, it can be presumed that they live.
- The games creator has said that the child was not intended to have a set gender, but it can be assumed they are one of the children seen in the photograph of their room. Many assume they are male due to the boyish look of their bedroom.
- In the game, the protagonist appears to have a dog, but is only alluded to through the appearance of a doghouse outside and the presence of dog food in one of the eggs. It can also be noted that a doggy dish is present in the basement.
