LEGO Disney 30720 Ariel & Flounder's Birthday Music Fun

LEGO set 30720, Ariel & Flounder's Birthday Music Fun, is part of the Disney theme, under Disney Princess. Released in 2026, it depicts a small Ariel and Flounder themed birthday music scene, with 39 pieces and 1 minifigure.

This set represents a compact scene from the world of The Little Mermaid, focused on Ariel and Flounder in a birthday and music setting. Within Disney Princess, it fits among small narrative builds that suggest a character moment rather than a large location or extended play environment.

It suits quick play, a compact display, or the addition of Ariel to a Disney Princess collection. Placed beside larger sets from the same theme, it can work as a secondary scene, offering a small, self contained moment that is easy to position with other Ariel related builds.
