Kim Byung Man tried to teach the two BTOB members how to make it up a hill but he utterly failed as he kept on tripping along the 'slippery' slope.  Embarrassed, the captain said, "I was just trying to be funny."  "It's not that slippery..." said Sungjae, trying his best not to laugh.

Soon, the trio found themselves face to face with a steep cliff, as the only way up was climbing on a bamboo ladder. "There's no end to this," Sungjae, examining the overall height they had to climb.

After the steep climb, they reached a nearby murky lake with a massive waterfall and they decided to take a break.  But the break didn't last long as a strong wind blew over, causing the members to take cover.
