The Magical Ocean Kingdom

A coral castle, a mermaid scout, and one very fancy seal court.

4.9 · 156 reviews

The Magical Ocean Kingdom is a 96-page underwater adventure where Marina the Mermaid and her dolphin best friend Finn explore a shimmering kingdom built of coral and shell. The book takes you through pearl markets where sea horses trade jewels, the Royal Seal Court (yes, with crowns), kelp-forest pathways, deep-sea bioluminescent gardens, and a final reveal of the Lost Library of Atlantis. Calming, flowing line work that's genuinely meditative for adults and beautifully colorable for kids. Some of the most-detailed coral pages in the series — perfect for older colorers who want to lose an afternoon.

Meet the heroes

The Marina & Finn story.

Every doodloo book is built around a pair of characters who spend 96 pages with you. These are the two you'll color again and again.

Marina the Mermaid

Marina the Mermaid

The kingdom's royal scout

A joyful mermaid with a seashell crown, a pet starfish named Sparkle, and a job that takes her everywhere — official scout for the Ocean Kingdom's queen. She knows every reef, every cave, and every fish too shy to come out.

AdventurousKindKnows every fish

Finn the Dolphin

The playful navigator

A playful, energetic dolphin who serves as Marina's ride, navigator, and best friend. Finn is wearing a tiny underwater scarf he knitted himself (don't ask how — dolphin knitting is its own thing).
