WaWorld is a home planet of the Wa-Guys. It exists "a long time ago in a galaxy far far away". It is a negatively-colored place that glows funny. But before all that, It was a boring planet with no living things in it, until Wario and Waluigi invented the Wa-inator to turn this planet into a "wa" planet. Now the WaWorld is the current location of the Wa-Machine.
