Rainbow Bubblegem 2: Secret

After the bubble gems lose their magic, peace returns to the sea, and Purple wishes to return to school on land, though the Purple King refuses. After persuading him, she declares her candidacy for queen and is permitted to go. At the start of a new semester, Purple loses her magic wand and princess dictionary while defending her friend Leo from the Blobs, Black Diamond’s henchmen. White Gold, the sea guardian, detects dark energy and gives her a new wand and dictionary. Using these, Purple crafts new bubble gems for the other princesses and enhances their magic, but cannot create one in her own color. The seven mermaid princesses, along with human allies like Gray, a senior of Leo’s, confront the stronger return of Black Diamond. Without her own bubble gem, Purple must find a way to protect both the sea and land.
