Some random guy meets a strange woman who is putting some kind of spell on him- night after night the suit forms around him and no matter how ofter he puts the growing pieces in the trash can- they still reappear- to the point where he can't get rid of the formed rabbit/bunny suit because of the lack of hands. So he sleeps for another night wearing the unremovable suit-
the next day the bunny/hare is complete and the woman happily takes her new "toy" in her possession
