Also, my frigatebird has a story of how it ended up in Lalotai. (Moana map seems to be Lalotai)
It’s a magical frigatebird, it can hold its breath.
It has the personality of Tamatoa, which can be described in one word and three exclamation marks: SHINY!!!
So its coin fell down into Lalotai. It held its breath to get it and fell into Lalotai too.
Now it has to avoid Kakamora, sloth monsters, geysers, holes, and friendly attack iguanas while trying to get back its shiny thing.
Everytime it collects 100 shiny things (coins) it gets a new friend.
