Life's not always easy for a Cactus. This particular one wants to impress his all-powerful dad with his epic magic skills, and he's not about to let anything stop him on his solo hero's journey. All he needs is a chunk of star rock to level up his potions. There's just one problem-there's none left. The only way to get a single slice of the stuff is to enter the deadly MotoBrawl race, find a way to stop accidentally turning bugs into giant fire-breathing creatures, befriend the lizard gangs that roam the desert, and maybe make a friend along the way. But does a lone hero even need any of this stuff?
