All around Zipper's bedroom lie the anatomy of myriad other species; muzzles, beaks, trunks, wings, hooves, shells, and even antennae can be found. Determined to cross the barriers of all cliques and classes, she adopts the guise of those she aims to meet. She will unzip her own paw to replace it with a flipper. When butterfly wings suit her purpose, they are only a zipper-pull away. Lest she forget her own Beagle parts, the spiderfairies that sewed and inhabit her interchangeable parts remind her. Without the labor of sewing up new skins, the fairies would be out of a job, so Zipper is sure to pay them in expensive orderves from her mother's catering business.
