In real life, Rudy's just a regular kid from a town called Plainsville. But Rudy's got one thing most kids don't: a magic piece of chalk that lets him enter ChalkZone, an amazing world where chalk drawings come to life. In ChalkZone, Rudy's an adventurer extraordinaire, battling monsters, rescuing damsels in distress (and, occasionally his pal, Penny), drawing up a storm and dreaming up schemes left and right. This guy's the ultimate daydream believer, because he can actually draw his dreams into reality in ChalkZone!
