Let your child learn in a fun way by completing vehicles and being rewarded with songs and sounds! Simply complete any vehicle to hear the chorus of popular children's nursery rhymes from CoComelon, including "The Wheels on the Bus" and "The Car Color Song." Your child will be excited to combine vehicles to create their own mix of "Fire Truck/Ice Cream Truck" or "School Bus/Fire Truck" and hear the new combination sounds. A mess-free water brush reveals hidden symbols in the vehicles. Like all WOW! Stuff officially licensed CoComelon products, the CoComelon Build & Reveal Vehicles set was developed in collaboration with Child Developmental Scientists. This ensures that the Build & Reveal Vehicles teach color recognition, problem-solving skills, and the development of hand-eye coordination. The set includes vehicles that are recognizable to your child, and when they are completed, the sounds act as rewards and stimulate cognitive behavior. Easy to use and energy-saving. In CoComelon, JJ and his siblings experience fun, relatable adventures. They go to preschool to play, explore, and learn. The videos not only help preschoolers learn letters, numbers, animal sounds, colors, and more, but also impart pro-social life lessons and provide parents with the opportunity to teach and play with their children while watching together.
