On Treasure Island, the arrival of Long Gone Silver and his pirate crew leads to unexpected chaos when they encounter Marina and her team of mermaids. When the Sacred Coconut disappears, tensions rise across the island, leaving the fate of its harmony uncertain. A singing parrot named Rita Conchita becomes central to restoring balance as both sides are drawn into a shared quest.

The production features a range of original characters including Long Gone Silver, Marina, Myrtle the shy mermaid, Isla the Queen of the Island, and Jack the Seasick Pirate. The creative team behind the production is not individually credited on the listing, but the musical incorporates calypso-inspired songs and salsa-style choreography to shape its storytelling approach.

Structured as a one-hour family musical, the production is staged at St. Martin’s Theatre in London’s West End. It presents a self-contained narrative designed for younger audiences and families, with music, movement, and ensemble-driven storytelling used throughout the performance.
