Baby Talking Tattletail, or simply Tattletail, is the deuteragonist of Tattletail. The toy brand was developed by Waygetter Electronics.
The player is supposed to receive one as a present on Christmas Day, but the protagonist opens it five days early in the basement. The player must take care of Tattletail's needs every night before they can return to sleep. In the Kaleidoscope campaign, Tattletail seems different and the player must figure out why.
