I voted "Other". for me, it was a toss-up between baby flutter ponies and baby windy/summer wing ponies. Teeny, stubby, shimmery translucent wings...
Speaking of which, does anyone remember that picture that an artist here posted several years ago of a baby windy wing that had no wings and six legs? It made a scary amount of sense, since the adult wingers have butterfly wings, and butterflies do start out as caterpillars..
