The plot centers around fountain master, Mr Whamsey, and the maniacal antics of Kiki the Hyperactive Monkey of Sentosa, both of whom serve as the show's main hosts.
In 1997, ECA2 commissioned the creation of Le Lac Aux Images to celebrate French theme park, Futuroscope's tenth anniversary.
[1] The show; which operated in Futuroscope's own musical fountain in France, closed down in 2002, the same year of Magical Sentosa's release.
Bang Productions managed the show's technical design[5] while Fischer Media Group was involved in an undisclosed role.
He shows off his skills to the audience, by first showing the fountain repeating his tune, followed by a grand orchestra piece, and finally a soft soothing water-themed song, (Water Waltz), but before he can finish a segment known as "Grand Finale", the fountain displays on both the terrace pools grind to a sudden halt.
Kiki then directs Mr Whamsey into a secret tunnel, which can be entered through the fountain's "SENTOSA" plaster sculpture's letter "O".
He is then forcibly ejected upwards in an animation similar to 'Le Lac Aux Images' and finally exits through the sculpture's "O", and compliments Kiki for the wonderful experience.
When he sings the last note completely out of tune, a fireball suddenly shoots up, awakening the Merlion who puts on a laser display for the audience.
The entire original soundtrack in high-fidelity audio was lost after the fountain's closure (apart from a recording of Water Waltz which surfaced in 2011), until an anonymous Singaporean YouTube user found a surviving copy in January 2013.
All tracks are written by Philippe Villar and Pascal LengagneOn 30 January 2013, an anonymous YouTuber by the username of, "caix92", rediscovered the album in its original entirety.
During Mr Whamsey's performance, he interrupts the "usual program" intended and appears laughing hysterically at the audience.
Afterwards, he introduces the surprised Mr. Whamsey to several of his friends, namely the mock band "The Fantastic Fish", and other unnamed characters.
Princess Pearl's sequence has been noted as the most remarkable as she was directly recycled from ECA2's earlier production, Le Lac Aux Images.
The band then reappears during the climax of the song and as they disappear from the scene, a mass of laser-colored bubbles shoots up in front of them.
As Magical Sentosa uses quite a number of references to Le Lac Aux Images, most of Kiki's friends and the laser-colored bubbles were actually from the latter.
Although not considered a prominent character, the Merlion statue located behind the fountain comes to "life" when Kiki sings the last note of, Here Everybody Lives in Harmony, completely out of tune.
The eyes of the statue emitted a green Stella Ray laser that shone down onto the fountain and when the song ends, it comes to take Kiki, who subsequently bids farewell to Mr. Whamsey and the audience.
[7] British author, Neil Humphreys, critiqued the interaction shown between Kiki and Princess Pearl as "infatuated" and "randy".
