On the February 8 broadcast of SBS's 'Laws of the Jungle', the cast members spent one night and two days on the island of Rota in the Northern Mariana Islands!

Made up of chief Kim Byung Man as well as Han Bo Reum, Ji Sang Ryul, Lee Tae Gon, Kim Yoon Sang, Lee Yeon Bok, GOT7's Yugyeom, and Nature's Lu, the cast divided up into small groups and went fishing or scavenging for food.

Chief Kim Byung Man, actress Han Bo Reum, GOT7's Yugyeom, and announcer Kim Yoon Sang noticed a powerful waterfall during their survey of the island. While Kim Byung Man and Han Bo Reum dipped their heads directly under the rushing waterfall for refreshment, Yugyeom and Kim Yoon Sang took off their shirts and started enjoying a freshwater shower!

Kim Yoon Sang discovered that standing under a strong, diagonal stream of water helped to deep cleanse his scalp, as the cast was going on two days without washing. Prompted by Kim Yoon Sang, Yugyeom also joined in on the deep clean, then expressed his contentment with a wave move in the water.
