Answer: Emerald
Yes, YNU Group Incorporated has produced a limited edition of 1000 Emerald Mermaids for Atlantis Paradise Island, a resort in the Bahamas. This new Emerald doll wears a blue-green metallic bra and matching cloth mermaid tail. I do not see any other accessories for her. Mixis fans and doll series completists can decide if this Emerald belongs in their collection. Since I am trying to scale back my collection, I will pass on this doll. I look forward to the new characters though.
