We might be not sure why Mama Tattletail was recalled, but I think she was recalled because of the gameplay of the Tattletale game. On the 3rd night, the player goes down the basement to find Mama. When you see the tape, you insert it into Mama. What if the tape was actually possesing Mama? That may be true because in the ritual, your suppose to destroy the tape in order to banish Mama so she wouldn't hunt you. So that must clearly mean the Tape is possesing Mama.
