Tiny Explorers

Ball runs built for the first year of play. Pieces are sized for little hands, with smooth rounded edges.

Drop a ball in at the top, watch it roll down, chase it, and do it all again — the simple loop toddlers repeat for hours.

Choose the two-tier Rollipop in pink or blue, or step up to the multi-level Rollipop Deluxe.

Ages 9 months and up.
