The game is about two creature races, the Splatians and the Corruptors, and their conflict about the mystical Rainbow Powder. They both believe that it belongs to them, they both do everything to study this substance, but the truth is that only Splatians can benefit from its true magic properties. Though, Corruptors are whatever they are named, and their pure evilness will turn an obstacle for the good will of Splatians. Or maybe not?
