Every mermaid has one too. I didn't create this design to win, (because I already have my own tail, hand made, but good enough.) but with the intention of giving if I win. If I win, the two extra tails will be given to dreaming mermaids, who can't afford their own tail. (Possibly even the third one.) Thank you in advance for your votes, and viel Gluck mermaids! Tchuss~
