From the update:
As we work on the first strech goal, i wanted to show you the consept sketch of the Mo'o. The Mo'o is the spirit beast that comes with the Hawaiian Koa Starter Kit.
The Mo'o is one of the most Common Guardian Spirits though out the cultures of the Pacific Islands. The Mo'o takes the form of a gekko, and it protects pools of fresh clean water on the islands.
