LEGO® ǀ Disney Princess Ariel & Flounder's Birthday Music Fun (30720) is a compact 39-piece Little Mermaid set for children aged 5 and up. It concentrates on a musical birthday moment, rather than building a palace, boat or underwater landscape.
Ariel and Flounder are the two Disney characters in the scene. The build also includes a sea-sponge pipe organ and a saxophone, giving the characters two distinctive musical props. LEGO does not describe a sound-producing mechanism: the instruments are brick-built pieces for pretend play.
The limited number of pieces makes this a short, small-scale building activity, not a full character collection or large castle. For broader Disney environments and other Ariel-themed designs, explore the LEGO® Disney sets.
