Fine, Scootaloo isn't a chicken she is a Were-Chicken! Once a month where the darkness of night is banished by the light of the full moon, Scootaloo transforms a horrifying beast that is both pony and chicken. Not even a griffon female in the middle of her mepienstrual cycle could match the terrifying wrath of the Were-Chicken. And although she swears she got stuck in Pinkie Pie's chicken costume last week, we know the truth. She is Were-Chicken.
