Dal Shabet probably had the most fun out of all the other girl groups while taking their teaser photos as they had a ball, literally, in a pool of white balls!

The group unveiled the photos on Naver Music's special event page to provide fans even more to look forward to as they prepare for their return. 

Dal Shabet will be making a comeback with title track, "Be Ambitious" (Korean title: "Look At My Legs"), on the 20th!
