From sitting & stacking to pushing & crawling, this little toy train is loaded with fun hands-on activities for baby to explore! There are 3 cargo cars to fill and 9 colorful, easy-grip stackers to load in and stack on top of each other. And when baby stacks the lion topper in the conductor's seat, the fun really gets chugging along! For more fun finger play, spin the roller bar to activate the engine's rattle bead smokestack. Little ones will love rolling this little train—and the stacking fun—along to their next play destination! Where development comes into playTM Fine Motor – As baby stacks the "cargo" onto the train, it not only fills the train cars, but it loads up their fine motor and eye-hand development, too! Sensory – The bright colors, rattling beads in the smokestack & fun textures on the stackers all help get baby's senses moving full steam ahead! Self-Expression – Baby will become a confident builder (and conductor!) as they learn to stack the lion and colored blocks in a variety of different ways!
