Kay Tokens (Lore)

Kay Tokens are a magical item that can make anything possible if you use them. This is proven to defeat Icky, use as payment, recover characters, and more.
They can also be found scattered around the Kay Kingdom. There are special ones there for some reason, and the scientists still don't know why these and here or how they appeared in these places and why the special Kay Tokens are exclusive to the megastructure.
Rumors say that if we collect all of the special Kay Tokens we may solve all of the questions we have now.
