H2o is adding another mermaid!!!!!! Thats right, another mermaid. 17-yearold Indiana Evans is diving into the hit montrer H2o just add water as the new mermaid Bella. Cariba (Rikki) and Phoebe (Cleo) are expected to return,Claire (Emma) will not return to the montrer because she is filming a movie. Unknown if there will still be a merman, how Bella became a mermaid, and if she will be good ou evil. I found this out in a link in this spot. H2o is to start filming in November at or Coast Austraila. Bella will be the newest adition to the group.
