Rainbow Bubblegem 2: Secret

A mermaid princess named Purple Star just wants to go back to human school and run for queen — school queen, not ocean queen, she's already got that covered. Her dad's not thrilled about it, but she talks him into letting her return to land. Things go sideways almost immediately when she loses her magic wand and princess dictionary while protecting her friend Leo from the Blobs, these weird minions working for a villain called Black Dia. Luckily, the guardian of the sea hooks her up with new gear, and now she can create bubble gems that power up the other mermaid princesses. The catch? She can't make one for herself. So she's out here boosting everyone else while being the most vulnerable one in the group, which adds a nice layer of tension to the whole thing. This is a 26-episode TV series aimed at kids, and the vibe is magical girl meets underwater kingdom with a distinctive CGI style that makes the ocean scenes pop. It splits its time between lighthearted school stuff and actual stakes when Black Dia's forces show up. If you liked the mermaid-princess-on-land dynamic of something like Wedding Peach or the team-based magical girl energy of Sailor Moon Sailor Stars, this hits similar notes. Fans of Yadamon: Magical Dreamer will also find the blend of whimsical magic and real-world settings familiar. It's colorful, it's got heart, and the bubble gem magic system is genuinely creative.
