Bill Myers 
Sky Surfing Skateboarder [EPUB ebook] 

Through a series of incredible mis-adventures (so what else is new), our boy blunder finds himself participating in the Skateboard Championship of the Universe. (It would be "of the World" except for the one kid who claims to be from Jupiter-a likely story, in spite of his two heads and seven arms.) It’s a tough crowd where anything goes as long as you win. Amidst the incredible chaotic chaos by incurably corrupt competitors (say that five times fast), Wally learns there is more to life (or in his case, near-death) than winning.
