With chakra work and superhuman strength, Jirōbō lifts up the very surface of the Earth. The lump of earth is gigantic and the destructive power is obvious. But even just the visual impact can be enough to make enemies lose their fighting spirits and run away. The ball of earth is then hurled at his opponent, flattening everything in its path.
The name of this technique may be taken from the Japanese art of Dorodango (泥だんご, Mud Dumplings), in which hard, polished spheres are made using nothing but earth, water, and one's hands.
