Winter is at its end but the days still continue to be cold. Laura’s Dad has heard, however, that flowers are starting to bloom around Shimmer Lake! So the family…and the Ham-Hams of course…all hop in the car for a weekend trip to hunt for springtime! But on the way, Laura’s dad take a wrong turn and the whole gang ends up in a cold, gloomy place rather than at Shimmer Lake.

When Laura says that she wished upon a star and her wish came true: that she got Hamtaro, Hamtaro is led to believe that he comes from outer space. His fears seem to be confirmed when Oxnard is apparently beamed up by a spaceship, but is there a more rational explanation for what happened?

Boss sees Bijou and gives her some flowers, but Hamtaro comes in and gives her a bouquet of flowers as well, and to Boss` surprise they are the exact same flowers Boss picked. Sabu notices Boss is feeling down, and tries to encourage him to keep trying to win Bijou.

Laura and her family have planned to go on a picnic together under the cherry blossoms. But like almost every year, her Dad is unable to come because of work. The Ham-Hams want to see the cherry blossoms too. On the way, they run into Auntie Viv, who is just back from her world travels.
