Roll, throw, split, step. These foam balls invite classic ball play for active indoor fun. Kept whole, they’re perfect for rolling games, gentle throws, and for babies to grasp and engage their senses. Split apart, the flat half-balls can be used as stepping stones, for obstacle courses, or stacking challenges. They also add character to your MODU creations as eyes, ears, headlights — or whatever you imagine. Enjoy them on their own, or connect them to your existing blocks to instantly expand the open-ended possibilities of your MODU collection.
