The Curse Of The Aquato

This curse is used as a punishment for humans who do things like killing young sea creatures, wear clothes made from the skin of sea creatures, etc. The curse appears to do nothing, until the target enters water, at which point, their skin hardens into scales, their flesh splits into gills, their skin turns blue, their hair falls out, and their legs merge into a single fin. The target is now a member of the aquato race, and the curse can't be reversed except by a wish spell, or a spell or magic item that changes a PC's race.

Notes: This spell is regarded as a cantrip, however, it fits better as a 5th level spell and the only reason I made it a cantrip is for lore reasons, ask your DM if you want to keep it as a cantrip.
