Endless Imagination For Your Child

Grindburst is a tough-guy, full of power. He uses one arm as a ground-breaking drill and his other as a sledge hammer. His might is in the details. This kid’s robot becomes a ferocious thunderbird with soaring wings and jet blaster claws, and a high-speed excavator.
