Every summer on Melemele Island, during the first thunderstorm of the seasons, teams of the island's toughest and bravest citizens venture outdoors to play the Togedemaru game. The teams have varied throughout history, and are rarely the same year to year; historically, they often represented rival factions of the Kahuna's court, but today they are as likely to be chosen on an east/west or north/south basis as to settle political issues.
The game is likely related to the Passimian game, sharing with it teams that seek to advance something round into a goal, but as the ball is a Togedemaru, it is too heavy to be carried or thrown – at least under competitive conditions. Togedemaru, for their part, see the game as a chance to mess around, and spend as much time zigzagging through players or rooted to the ground as they do moving in ways anyone in game intends; nine Togedemaru are sent to the field at the start of every match, and new ones are released not only after goals, but when both captains agree the prior Togedemaru in play is lost. At times, however, the lost Togedemaru was simply hiding in tall grass, mistaken for a large rock, or fled, but returned to the playing field of its own volition, leading to a confusing situation with multiple balls in play.
The Togedemaru game likely grew out of festivals dedicated to Tapu Koko, which is reflected in the conditions in which it is played. Togedemaru are natural lightning rods, so the game is not quite as dangerous as outsiders imagine. But stray lightning bolts can indeed hit players too far from the ball, or even those contacting it at the wrong angle; these hapless victims are understood to be sacrifices to Tapu Koko.
