Jung Jun Ha tweeted on the 14th while filming for a broadcast, "Under the daytime temperature at Yangju, Gyeonggido of 32? [89°F]..Nora Pop!!?? Bora Pop??!!^^."
Posing in front of a firetruck and ambulance while dressed in public service uniforms, Jung Jun Ha and Bora get in position to join in on the fun 'Bar Bar Bar' dance. They're joined by Crayon Pop, who have no need for extra safety equipment thanks to their helmets and gloves.
With everyone joining on the craze, fans are left wondering who will be the next celebrity to start 'jumping' with Crayon Pop.
