Mary saw two vials marked with a picture of a dragon, so she closed her eyes and picked one at random, and drank half of it.
Her body suddenly grew green scales all over, and grew bigger all around destroying her clothes. Now she was roughly 6 foot 8 inches, and then her skull reshaped forming a dragon head, teeth, eyes, and horns. Next she grew wings and a tail which was not as painful as Mary thought they would be. Next her hands, and feet changed to form 4 digit claws, thankfully she still had her thumbs.
"Oh wow this is different," Mary said looking in a mirror. Mary picked up the note and it had something on the back saying,"if you plan to use multiple vials we only ask not to use vials of different species on yourself, and to not let the contents go to waste."
"Hmmmmm," Mary said taking the case downstairs,"I wonder who will join me next."
