Dive into the sea with Pop the dolphin, and roam the land with Billy Bisson the bison. Two big-hearted worlds of discovery, real science, and the kind of friendship that lasts forever.

Four unforgettable friends from the depths of The Sea, each one a little different, each one exactly what you need.
Turquoise, brave, and endlessly optimistic. Pop believes every wave hides something extraordinary. First one in, last one out.
A grey seagull with zero patience and a secretly enormous heart. Complains constantly, shows up every single time.
A softly glowing jellyfish with ancient knowledge and perfect timing. Says exactly what you need to hear, just when you need it.
An orange hermit crab who has changed shells 47 times this season alone. Anxious, hilarious, and somehow always helpful.
Every world begins with a book. Big-hearted, real-science picture books set in Atkinson Hyperlegible, so every kind of reader can dive in.
Pop has taken the leap from the ocean to the racetrack. Popphin Performance is the official Formula GP team that carries the spirit of The Sea into motorsport, bright blue and coral livery, a dolphin on the cockpit, and the belief that going fast can still be fun.
