Recently, Hamtaro has been plagued by an odd dream in which a beautiful princess hamster weeps, pleading for help. The memory of her lingers even when he is awake. One winter day, his friend Laura confides that everyone in her family is heading back to her father’s hometown. When Hamtaro shares the news with his friends, Maxwell pulls out a Ham‑Ham source book, an old volume of hamster history. The book reveals that the “homeland” for hamsters is called the Hamja Kingdom. By building a sand castle and reciting the spell exactly as written, the hamsters are transported to that kingdom. Finally, the group arrives at the bustling Hamja Kingdom, where the well‑known King Hamj awaits them.
