Dragon Balls with black stars inside, made before Earth's God and Demon King Piccolo split in two, which hold a greater power than regular Dragon Balls. Pilaf uses these balls to transform Goku's body into that of a child's. Using these will summon forth a red Shenlong to grant a wish. The black-star Dragon Balls will then scatter across the cosmos, and if they are not assembled within one year, Earth will vanish. Unlike regular Dragon Balls, after the wish is fulfilled, they do not seem to turn to back to stone.[1]
