On August 11, KBS revealed photos of Girls' Generation's Sunny, EXID's Solji, Melody Day's Chahee, LABOUM's Solbin, G-Friend's Yerin, and Gugudan's Kim Se Jung splashing around near a swimming pool. Solji looks quite tired, Sunny appears as if she can't believe what just happened, and Kim Se Jung is all smiles despite being drenched.

The girls will be playing a game of 'Don't Laugh Sauna' as well as 'Tray Karaoke' on the show, which airs on the 11th at 11:10PM KST! In the meantime, check out the preview photos below.
