The story celebrates a kid’s sense of wonder, and the witty, evocative lyrics from Tom Paxton’s classic song spark your imagination and insist you join in: “It went zip! when it moved, Bop! when it stopped, and Whir! when it stood still!” The incredibly bright retro illustrations lift the story to a whole new level and now, MobiStories literally bring the song and almost everything on the page to life with a simple touch of your finger! The toy shines, spins and makes funny noises, UFOs fly around, trucks move back and forth, characters speak! Even the song itself has been given a light-hearted 21st century musical makeover to add to the overall wonder!
