More photos featuring SISTAR for their 'Ocean World' endorsement have been released.

As the water park's new sexy endorsement models, the ladies showed off their bikini-ready bodies in high heels, sheer cover ups and shorts. The hot photos make you want to cool off by joining them at the park. 

A representative from Ocean World commented, "Soyu, Bora, Hyorin, and Dasom, all have singing ability, stage presence, beauty, healthy figures, charisma, variety show skills, and more. We selected them as endorsement models because they fit well with the water park's special charm of giving thrill and excitement through water-related activities. We anticipate a synergistic effect between the opening of our new water ride, 'Super Wide River', early this June which coincides with SISTAR's upcoming comeback."
