The ONCE Show (or Once Show) is a multimedia real-world performance lasting about 20 minutes at VinWonders Phu Quoc. The show was produced by Quantum Creative Studios (USA) – a creative agency that has participated in many projects for The Walt Disney Company, Universal Pictures, and Marvel Entertainment. With a total investment of nearly 12 million USD, this is considered one of the large-scale and unique real-world shows in Vietnam.
The show's content revolves around the confrontation between good and evil in a fairytale world. Audiences will follow a hero on an adventurous journey through many imaginary lands to face a powerful witch, aiming to reclaim the Fire Phoenix Feather Pen – a symbol that can write a happy ending for the thousand-year-old fairytale book. Throughout that journey, many unique characters such as the fire phoenix, Pearlie the monkey, or the dark witch are vividly recreated through a combination of live actors, puppetry, and modern stage effects.

The impressive point of the ONCE Show lies in its large-scale technology system and stage effects. The show utilizes over 39 fire nozzles up to 61 meters high, hundreds of fog machines, and a high-tech projection system to create 3D mapping, smoke, fire, ice, and water effects. All are combined with music, laser lighting, and fireworks, delivering a powerful visual experience for the audience.
