This is one of those "the title explains itself" sort of situations. SPRay is short for Spirit Prince Ray, the protagonist of this Wii-bound action-adventure, and spraying various liquids and goo around is what he does best. Here's the premise: His highness' crown grants him the ability to summon two spirits -- one is good, and the other is evil. Each spirit has its own arsenal of liquids: The devil has antimatter, vomit, and, um, snot; the angel uses water and ice (yeah, it's not a liquid per se). Using the Wii Remote as a pointer, you spray people and places with different liquids for zany results.
