The Ohana Isle Hunt start location can be found here .
These guys have a very clever script to help you locate the items.
The items your looking for are small pieces of Sushi.
They have hover text over them so they aren't hard to spot
I am not doing hints for this hunt, as I want to see if the script helps.
It tells you store name and if there are multiple keys in that location.
Please go enjoy this hunt and the technology they have made. Please give me feedback on opinion.
