Moana & Island Living: Hints to some secret details?

I have actually noticed it, and I'm planning to create Moana herself as a mermaid and the mayor of Sulani. If I remember the CAS section of the stream right, there's even the exact same necklace Moana is wearing in the movie. I don't know if that was intentional, though, since I don't know anything about Polynesian culture and fashion. Maybe Moana and Island Living simply drew inspiration from the same source rather than one being a homage to the other, but if it was, that would be awesome.
