Most of you probably never hear about they because they born on latinAmerica so let me explain you:
Fabio yabu is a Brazilian cartoonist, comics and book writer. In 2004 he publish "Princesas do mar" ("Sea Princesses" in english), In 2007 Yabu with "Neptuno Films" produce a animated serie based on this books; The animated serie was transmitted on the United Kindom, Spain, Mexico and other 47 countrys (Not in United States apparently).

It wasn't the most popular serie, but I like it very much, and I'm surprised about the less fan art material that you can find of this characters, considering that the "Princesas do Mar" Franchise have much more of 30 characters most of them females with creative outfits/swimsuits it's a real shame that this characters never arrive to other countrys

The name of the characters are:

Pulpina(Mexico)-Pulpita(Spain)-Polvina(Brazil)
She is the one who had the pink octopus


Tiburina(Mexico)-Tubarina(Brazil & Spain)
She is the blue one wich have the shark hat (She is my favorite)


Ester(Mexico & Brazil)-Estela(Spain)
She is the one with the yellow starfish on the head

I really love this characters, and they are a lot, so if you want a pic of this characters (or the rest of them) ask for it, I'm not doing requests, but if you have a good idea I can consider it
