It's a mermaid, it's a unicorn, no ... it's both! That's correct, our Tokidoki Girls Mermaid Mermicorno Hood tops off little girl's costume of this wildly popular Tokidoki character. Never has tick-or-treating been so much fun. She's swim through the ocean and fly through the night when she is dressed up as Mermicorno and topped off with this hood with attached ears!
