An impromptu example of the Chu Chu dance
Lower Deckers witnessing the Chu Chu dance
The Chu Chu dance was a dance of the late 24th century.
Beckett Mariner saw the Zebulon Sisters perform the Chu Chu dance at Deep Space 3.
In 2380, the Chu Chu dance was again performed by the Zebulon Sisters aboard the USS Cerritos, where it was witnessed by Ensigns Beckett Mariner, Brad Boimler, and Karavitus. Around this time, a third "Chu" was added, and it became the Chu Chu Chu dance. (LD: "Terminal Provocations")
In 2381, Sam Rutherford hummed the Chu Chu song while playing the holo-novel program Crisis Point II: Paradoxus due to it being stuck in his head at the time, much to the chagrin of D'Vana Tendi, who was attempting to take the program more seriously. (LD: "Crisis Point 2: Paradoxus")
