Spherehedz adds a fun twist to collectible action games with sphere-shaped characters that transform as you play. Use the power spinner to set each Spherehedz in motion and watch as it spins open to reveal a surprise design inside. Launch them into the included 11-inch arena, quick and easy to set up at home or on the go, and enjoy the excitement of battle as characters spin, bump, and react to each other. The last Spherehedz to stay open wins the round. Series 1 has three collectible 2-packs, so kids can mix and match characters for lots of different play experiences.
