Extended: Cole awakens inside an icy cavern where he mistakenly assumes, he has been imprisoned by the beast, Krag. The creature returns as Cole is attempting an escape and another fight ensues. This time, Cole wins and Krag is imprisoned. Cole runs for the mouth of the cave... where he stumbles upon an icy cavern full of burial mounds. Realizing that Krag once had a family and that the beast is lonely, and wasn't trying to attack him but save him, Cole returns and releases Krag. The two become friends. Despite the fact that Krag and Cole does not speak the same language, Cole is able to convey that he is looking for the Traveler's Tree. Krag carries Cole on his back up a steep cliff and delivers him to the peak where Cole finds the magical Traveler's Tree! He plucks some leaves and they return to the cavern where Nya and Jay lie in wait. The ninja attack Krag, assuming the creature has imprisoned Cole. Cole intervenes at the last moment and explains the truth: Krag is his friend. Not wanting to leave Krag alone, Cole invites the creature to return with them to the village. Krag says farewell to his cave and follows the ninja down the mountain.
On a chilly night, Cole and Krag are fighting each other. At first, Cole is successful in his attack, but Krag gets the last laugh when he knocks Cole unconscious using a stick.
When Cole wakes up, he finds himself in Krag's home. Cole heads for the exit, but retreats and hides from Krag. When Krag enters his cave, Cole strikes him and is able to bury the beast with a massive stalactite.
As Cole explores, he realizes there are bunk beds and burial mounds indicating there were multiple Yetis living inside the cave and they somehow died. When he realizes Krag is the last one, he realizes he made a mistake in fighting him and decides to help him.
Upon seeing Krag stuck, he spots a tree branch holding berries. He realizes Krag was supplying food for him. When Cole asks why he's the only one, Krag growls at a discarded crossbow used by the Blizzard Samurai. Cole then comes to the realization that the yeti were killed by the Samurai. He also then realizes Krag was saving him when the bridge was collapsing, and not trying to harm him. Afterward, Cole lifts the block of ice and frees Krag. As a result, the beast hugs Cole as he found a new friend.
Subsequently, Cole asks where the Traveler's Tree is, so Krag gallops ahead of Cole. When Krag realizes he left Cole behind, he returns to Cole and they ride together until they reach the peak of the mountain. When they reach the top, Cole grabs some flowers, and they descend downwards.
Eventually, Jay and Nya reach Krag's home and spot Krag arriving home with Cole. When they enter the cave, Jay and Nya get into a brawl. Luckily, Cole is able to end the fight and introduces Krag to Jay and Nya. Cole then offers Krag a new home and he gladly accepts.
The ninja and Krag head down the mountain, but Krag stops for a moment and admires his home that he has lived in. He then places a branch into the snow and howls, promising to fight for the Yeti who were killed by the Blizzard Samurai.
