Every katamari starts off with a magical ball at its center. This ball is highly adhesive and allows anything smaller than it to stick to it and make it grow. This glue must transfer to the objects that come into contact with the katamari, as the ball itself soon disappears within its ever-growing clutter.

With the alien property of everything sticking to it, yet it not sticking to the ground, a katamari is truly a mysterious specimen. Virtually indestructible and waterproof, the katamari is an extremely hard object to rid the world of. Your target is the one controlling the katamari; the Prince.
