Gently twist apart the Oreo Thins. Then scrape off and discard the filling from the cookie. Break each of the cookies in half by hand.
Place a dab of chocolate frosting on the backside of a corner of each cookie half, in order to attach it to the top of the Reese's cup for the wings. The rounded edge of the cookie is at the top and the frosted corners meet in the center of the top of the Reese's. (See pics)
Use a dab of frosting on the backside of the candy eyeballs to attach them onto the inner corners of the cookie wings. Enjoy!
