You were a species of merfolk and you had taken interest in the dry world, spending hours watching the shores. You had once heard of a sea witch that may be able to grant you the legs to yurned for. You wandered into his cave, passing shelves of jarred critters. He ignored you as you first entered but you kept pleading. He suddenly spun around, wrapping his tentacles around your tail and taking your chin into his hand, "You don't seem to know how this works, doll; I need something in return."
