Daring Do and the Mirror's Curse

Last thing on the list? Feather of a Cockatrice. Those are in the Everfree forest. Head of a chicken, body of a snake. This’ll be tough.

The Everfree forest was nearby. She went in there, and heard three little fillies saying, “here, chick chick chick...” and “Scootaloo, scoot, scoot, Scootaloo!” they seemed to be looking for a chicken. Great. Now she’ll get all confused.

She looked around, and saw the top of a chicken. Whoop! But when she tried to get a feather, it turned out to be a chicken feather. But then she saw a snake tail, and tried to pull it. Dang, real snake. Until she came across a pony, who looked like that purple unicorn who thought her rightness was a doozie, but she was stone. And then she saw... that yellow pony from earlier? Must live in Ponyville. She was yakking to... something with a head of a chicken and a body of a snake. WHOOP! She just wanted to reach in and grab it, but didn’t want to be seen.
She waited for the other Pegasus to leave, and just took that little feather that creature left when it ran away. Last one!
