1 Night 2 Days casts visit Everland Theme Park.

Guest actress Kim Yoo Jung joins the cast of 1 Night 2 Days to visit Everland Theme Park located at Yongin in Gyeongi-do. The casts and guest have to play bok-bul-bok game to decide who will be sleeping indoor or outdoor in this cold weather.

PD Yu informs them the shocking news that the 2 losers will be sleeping together with the 'lions' in the safari park! The utterly shocked look on their faces. First game was riding the Let's Twist where it looks like a 5 hairbrush with the seats turning at 360° in any direction.
They are to gulp a cup of orange juice during the ride, do not drink it or spill it out. For those who drink or gulp down the drink will be the loser. Sure enough the twisting ride drove everyone mad as they couldn't laugh or scream with the orange juice inside their mouth.
Defconn's grunting sounded as if he was giving birth on the twist ride! LOL! At the end, Yoo Jung turns out to be the loser as she drank the orange juice. Jong Min turns out to be the winner.

2nd mission was to ride the T-Express roller coaster ride while counting 14 pieces of KRW$1000 bill. Tae Hyun managed to bluff his way to Jun Ho encouraging him to sit at the last row which turns out to be the scariest of all. Yoo Jung sat in the front with a VJ and two PD's were in front of her as well. T-Express is considered one of the steepest wooden roller coasters in South Korea with 77 degrees angle of height. 

Defconn and Shi Yoon were seated together crunching their faces as the roller coaster drops down at a split second. They were busy counting their dollar notes and freaking out as well. In fact Defconn's face expression was uglier than ever. Shi Yoon was looking happy while Yoo Jung remain calm and pretty counting the bills.

Jun Ho's mouth was gaping away while Tae Hyun was merely enjoying the thrilling ride screaming away happily! Hah! In fact Jun Ho's dollar note flew away a few times which means he lost his money in the ride. Due to safety reasons, the production crew manages to collect back the dollar bill. 

After the ride, Jun Ho looked 10 years older and said he rather be sleeping with the lions than taking the ride again. He was the only one who didn't manage to count all the 14 dollar notes. Third and final mission was boarding the water ride called Thunder Falls. It is one of the latest attraction featuring a signature turntable and backwards drop. The rafting has reversing room, where riders enter backwards and shoot out facing forwards. This ride features a single tower where all of the ride’s lifts and drops converge, smartly using the hilly terrain. 

Each of them have a big and cute looking candy floss looking like 'Corny' from Line Friends. They are to avoid the candy floss from being destroyed in the water ride. Sounds ridiculous right? Indeed! Tae Hyun sat in the front hoping to avoid at any damage to his candy floss. Jong Min and Jun Ho stood aside since one is a winner and another is the loser.

The big splash of water nearly destroyed their pretty looking candy floss. However Shi Yoon's one turned out disastrous so he had to sleep outdoor with Jun Ho. The two headed to a tent pitched up nearby the lions den. Jun Ho had to get re-assurance of the 5 lions been kept in the cage...just to be sure... Of course under the safety from the keepers and crew, the two managed to sleep with howling voices from the nearby animals. The next morning Yoo Jung woke all the members up. They laughed at how Jun Ho was startled upon seeing few giraffes looking at them strangely. Even the lions at the opposite site were just lazing away.
