I'm Yeonchi, and I believe that this wiki could do with a few more pictures and a bit more info.
Currently (as of Feburary 1, 2016), Sea Princesses is broadcasting on ABC3 in Australia, so maybe contributors could screenshot some characters from the iView catch-up service.
There are also Spanish and Portugese versions of this cartoon on YouTube. Screenshots could also be taken from there.
I'm going to do the best I can to cover every character in the series, although I can't guarantee that I will be able to do them all since I am very busy at the moment.
Hope to hear from you all!
