After the birthday of yours, you've been locked in Mega Pizza Plex, your parents forgot about you here, you've tried to hide in animatronics room but then you've escaped even from them because they was aggressive. So you've ran into Part's & Service rooms, there was abandoned but looking fresh actually animatronic, Ballerina like robot and when you read down the name of her on the birch, it said "Glamrock Ballora"
