You are Toy Chica, one of the many fnaf animatronics... and no, you aren't the original child who possessed the animatronic, but other than that, you wake up on your stage as usual, and you see Mangle Sleeping, Toy Freddy doing singing Practice. And Toy Bonnie is making songs with his guitar

Toy Freddy: "Why can't I sing this song..."

Toy Bonnie: "Shut it Toy Freddy I'm trying to focus!"

Mangle: "sleeping"
