Wahu Phlat Ball is a unique sports toy that transforms from a 9" flying disc to a 6.2" fun ball when thrown. Its variable time-delay transformation adds a twist to the classic outdoor game of catch. It also packs flat, so it's easy to slip into a backpack or suitcase. If it lands on a sloped roof, it pops open and rolls right off - it's not a flat ball for long! Throw a disc, catch a ball! For 1 or more players, ages 5 and up.
