Preschool wagon play meets buildable, shape-sorting fun! Discovery takes shape with Mega Bloks First Builders Shape Sorting Wagon! Toddlers can learn to identify shapes when they wheel out a colorful wagon with a shape-sorting twist. Match the specially-shaped building blocks with their outline on the shape sorter to send them clunking into the wagon's bin! Use the easy-to-grip handle to roll the wagon along on its big wheels, hauling your blocks as you go. You can even build right onto the wagon! Stack, sort, and roll to learn your shapes as you build and play!
