Kkoma Bus Tayo-ui Ace Guchuljakjeon

Duri accidentally drops his favorite toy sports car, Ace, while running outside. Rubby finds it during street cleaning, mistakes it for rubbish, and sends it away with the trash before anyone realizes what has happened.

Tayo, Hana, and Duri follow Ace to the Land of Toys, a hidden place where lucky abandoned toys live without humans. Bringing him home requires crossing a world with its own rules and convincing its residents that Ace was lost, not discarded.
