KARA recently performed live at a special event in Tokyo for KDDI's running and walking service called "auSanta's Challenge". Bringing their Christmas spirit to the event, the girls performed their famous butt dance for "Mister" as well their new single "Jumping", before changing into cute Santa outfits. Jiyoung stated, "(The Santa cosplay) was embarrassing at first, but it's okay now." When Seungyeon was asked how she felt about working around Christmas, she answered, "I'm sad, but it's work."
