Mason and Emmett were two little boys, who were the sons of Princess MeMe and Prince William. They lived on the magical island of WaWa, which was located in the Hawaiian Islands and invisible to the rest of the world. The peaceful life of the island was soon upset when an evil king named Maka Maka tried to take over and rule all the Hawaiian islands, but these two boys saved their island and all the Hawaiian islands from this wicked King.
