Letter Lagoon
Meet each sound and the letter that makes it.
Coming soon
Rosie's world is the Sunken Library, where letters and sounds drift on the current. She helps children hear, blend and read their very first words.

Every sidekick has the same two pieces of Coralis engineering, tuned to them and built in the Lab by Albert, Debuggy and Nala.

A sea, land, flight and space craft in Rosie's colours, call sign ROSIE. Rosie floats in the water-filled cockpit; a hull camera on a gimbal feeds the Viewport.
Tuned to sounds and letters, the Viewport shows the words Rosie is reading as she sounds them out.
Close to home in the library, where reading begins.
Meet each sound and the letter that makes it.

Between adventures Rosie is home in Coralis, the advanced city on the seabed where the whole Pod lives. Each sidekick has their own base there, and they share the Lab where the Bubblecraft and Viewports are built. Home never changes; the destinations always do.
