Do we have any idea about Oricorio's type distribution between islands? Personally, I see the Sensu Oricorio will be found in the south-eastern island; the one that includes Tin Tower alike building.
My guess would be Pom-Pom on the starting island, Baile in the northeast, Sensu in the southeast, and Pa'u in the southwest, though I am only super confident in the first guess.
