Kids attending Denver’s Green Frontier Fest on August 24—the eve of the 2008 Democratic National Convention—were the first on the continent to experience the very latest in eco-friendly playthings. Sprig Toys, Inc. of nearby Fort Collins invited children to play with the Sprig Adventure Series, a new line of kid-powered and totally green vehicles for preschoolers that recently began shipping to specialty toy stores across North America.  Made from Sprigwood™, a child-safe, bio-composite material derived from recycled wood and reclaimed plastic, the new toys harness the natural energy of push- and pump-action play to power lights and sound—all without batteries. Adventure Guide characters plug via USB into durable vehicles and engage preschoolers with audio that guides them through exciting adventures as they play. And, perhaps best of all, the toys fight childhood obesity—the electronics only work if a child is actively moving a vehicle.  “Sprig was proud to be a part of the Green Frontier Fest and focus attention on the need for safe, earth-friendly and active toys,” says Chris Clemmer, co-founder of Sprig Toys. “As a toy designer and father, I want to see America’s kids get off the couch, learn to use their imaginations and help us save the planet.”
