Winter comes, and all the pine trees that Ai has planted have fully grown and are decorated with Christmas lights. A spaceship crash-lands in the middle of the forest, and Johnny, a seagull, emerges. Johnny, who had planted the bottles in order to make an entrance dressed as an alien, asks the villagers to help locate some of the pieces that broke off his ship during the descent. Ai, Bouquet, Yū, and Albert head towards a cave, where Yū claims to have seen one of the pieces fall. The entrance, though, is blocked up by a large boulder from a recent event. Though the team tries to move the boulder, it eventually turns out it is too heavy for them to move. Sally then appears and helps unseal the cave.
