Dragon Ball Z - Scultures Big Zoukei Tenkaichi Budoukai 4 "Polunga"

Polunga was the Eternal Dragon of Planet Namek summoned when all the Dragon Balls of Namek are gathered. Compared to the Earth Dragon Balls, the Namek Dragon Balls are quite large, being more towards the size of a basketball rather than the size of a small grapefruit. Also, since a year on Namek is only 130 days (as opposed to a year more than twice as long as that on Earth), the Namekian Dragon Balls can be gathered more often than the ones on Earth, and thus, Polunga can be called on more often than Shen Long.
