On the January 25 airing of SBS's 'Laws of the Jungle' in the Northern Mariana Islands, the cast members split up into small-sized teams for an even more challenging survival trial. Former/current idols Oh Jong Hyuk, Cosmic Girls's Bona, and The Boyz's Jooyeon went off as a team of three. 

In the evening, the team's resident "dad" Oh Jong Hyuk set off with the staff for night-fishing to feed his "children", Bona and Jooyeon. The two idols then set off on foot to search for dinner on land. 

While walking in the dark, Bona asked Jooyeon how long he practiced as a trainee. Jooyeon replied, "Practicing under a company... about 3 years?" Bona shared, "For me, it was a total of 5-6 years." Bona then mentioned, "I think that's why we enjoy this program more, because we haven't had many opportunities to travel." Jooyeon agreed, "Right, we never had time." 

Bona also revealed, "The thing I like the most about the jungle is not knowing what time of day it is." But in the middle of discussing their trainee lives, Jooyeon and Bona discovered a huge coconut crab, hidden in the grass! Watch above to see the two idols rejoice over their first real catch, and check out additional clips from this week's broadcast below.
