Ollie is jumbo fun that grows with your baby! Ollie has 3 ways to play: 1) Light-up buttons and sounds teach numbers, colors, and shapes to sitting babies. 2) A flip-up handle and speed control keep little walkers moving and discovering. 3) Lower the seat when your growing toddler is ready to roll. Versatile ball play includes put-and-take action in the seat and popping and scooping on the go.
