Booma is mortified when Bad Inc.'s shrinking potion reduces his colossal keister to the size of an average man's booty. He soon begins to realize, however, that it's not the size of somebody's backside that matters.

Kimo develops an obsession with miniature golf that leads the Sumos to uncover a dastardly Bad Inc. plot to control the minds of youngsters. Can the trio prevent Bad from turning kids into mindless automatons?

Mamoo, Booma and Kimo are three 18-year-old, 1,000-pound sumo wrestlers, dressed as per custom in super-hefty-size sumo thongs. In addition to their bulk, they pack ancient sumo powers, which makes the modern world a bit confusing for them. But when evil threatens, the three flex themselves into a dramatic physical transformation, doubling their size and strength. (If only their brains grew, too!)
