The Bubble Buddy Walker Wagon is the perfect beginner walker to bring bubbles and smiles to your child! Our bubbles are kid-powered – no batteries required! Bubbles will blow as the back wheels move, whether it’s pushed or pulled. The handle locks into place to provide support for beginner walkers. When they’re ready to pull the wagon, simply unlock the handle to transform it into a pull wagon. One bottle of bubble solution is included and the bubble reservoir is compatible with any standard bubble solution. Recommended for ages 1-4 years.
