SBS’s “Running Man” has released an exciting preview of its upcoming episode!

All four members of MAMAMOO will be appearing on the next episode of the variety show, along with actress Shin Hye Sun, actor Sung Dong Il, and comedienne Jang Do Yeon.

The newly released preview introduces the guest stars as “elite auxiliary forces” who will be lending their support to the “Running Man” cast during the episode’s special “Protect Your Name” mission. The MAMAMOO members appear to be having a blast as they bring their unique energy to the show, dancing wildly with HaHa and making good use of a karaoke machine. HaHa also describes Hwasa, who hungrily munches on some food, as a “rising star in the mukbang [eating show] world.”

Sung Dong Il, who recently starred in the hit film “The Accidental Detective 2: In Action” with Lee Kwang Soo, shows off his chemistry with his co-star by savagely joking around with him. In the preview, Lee Kwang Soo turns to the camera and threateningly tells his opponents, “If you cheat, you’ll get hit!” Sung Dong Il responds by playfully smacking him and saying in an exasperated voice, “You’re the one who should get hit!”

Jang Do Yeon displays some impressive toe strength and flexibility as she pinches Kim Jong Kook’s ear with her toes, while Shin Hye Sun, the star of SBS’s new drama “30 but 17,” gets passionate about her mission on the show.

The “Running Man” cast then takes their battle to an octagonal ring, where things get a bit messy—both literally and figuratively—as Jun So Min accuses Lee Kwang Soo of betraying her by breaking a promise.

The next episode of “Running Man” will air on August 5 at 4:50 p.m. KST.
