>>27296204One problem: the westernmost island has only one village.
I got to thinking of the platform that Tapu Koko is being summoned on, and searched for something like that on the other islands. I only really found another such possible place on the big island. Then I looked at the westernmost island's village, and how it apparently has a tree in it. One of the colors of Kukui's hat is green, and if the islands are following the gen 1 colors, then there is a green guardian. That must be for it. However, this is where my efforts failed because not-Maui doesn't have anything that I can say is a spot to summon a guardian, save for the giant active volcano. (red) Anything that could be said to be the platform on the big island is associated to water. (blue) I'm kinda skeptical about this since Hawaii is more associated to red, and while that still may be true, there is little to suggest water on not-Maui, save for the water building and the hot springs.
