Yoku's Island Express follows Yoku, a carefree dung beetle who arrives on Mokumana Island to take up duties as the new postmaster. But the island god is trapped in a nightmare-induced slumber, causing storms and tremors that threaten the land. As Yoku rolls through an open world packed with pinball-inspired traversal, he must awaken the ancient god, help eccentric islanders, vacuum explosive snails, feed starving lemurs, and restore the dilapidated post office. Beneath the whimsical visuals and light-hearted tone lies a metroidvania-style adventure that reveals island secrets and unlocks powerful abilities on a journey of tiny heroism.
