Rainbow Bubblegem 2: Secret

When the magical bubble gems scatter and their power fades, peace is restored to the ocean. Princess Purple longs to return to her school on land, but the Purple King firmly opposes the idea. After much persuasion, she declares her intention to run for queen and finally earns permission to surface. However, at the start of a new semester, disaster strikes when Purple loses her magic wand and only princess dictionary while defending her friend Leo from the villainous Blobs, loyal subordinates of Black Diamond. Sensing the rising dark energy, White Gold, the guardian of the sea, gifts Purple a new catcher and princess dictionary. Using these tools, she crafts new bubble gems to upgrade the magic of the other princesses, yet mysteriously fails to create one in her own color. United with the seven mermaid princesses and new human allies—including Leo’s senior student Gray—the group faces a returning, more powerful Black Diamond. Without a gem of her own, Purple must find the strength to protect both the ocean realm and the human world above.
