Description After surviving a long, cold winter out in the wide world beyond the nostril, spring has finally arrived for Coji and Cobi, the lovable booger siblings. Tiny green leaves huddle together, whispering of the fresh new season, and even the occasional breeze feels warm and gentle. For the first time in their lives, Coji and Cobi are utterly delighted by the cozy feeling of spring. The day of their long-awaited cherry blossom picnic finally arrives, and the boogers are busy getting ready from the moment they wake up. They hurriedly pack snacks and water, excited for the day ahead. But just as they're about to leave, Coji can't stop looking back, worried about Grandma, who caught a cold and has to stay home. The road is already packed with other boogers who've come out to see the cherry blossoms. Squeezed and jostled from every side, Coji, Cobi, and their uncle get separated in the crowd—and suddenly realize that Coco is missing! As the family searches frantically, a terrifying thought creeps in: what if they never find Coco again? Where could Coco have gone? Will Coji and Cobi manage to find Coco safe and sound, and finally enjoy the cherry blossom picnic they've been looking forward to for so long?
