21 parts Complete Two friends who were training to be professional merfolk become real merfolk one of them autistic. They are on the big adventure of their lives to save the world. Note I don't own H2O Just Add Water or Mako Mermaids all copyrights to these shows belong to Jonanthan M. Shiff Productions. I wrote this story because I was inspired by my friendship with someone who I'm close friends with, the fact she and I are working on becoming a professional merfolk, and we like both shows. Plus I also wanted to make a character with autism for the H2O universe not to mention I also wrote this to help me deal with anxiety.
