|“You never said that. I said that! I said 'How could there be fish on a mountain?'”|
|— Uthaug arguing with Boma in "The Traveler's Tree"|
He and Boma were walking down a path carrying fish and discussing how to pronounce "Ninjago" when they hear someone marching their way. After realizing it's the Blizzard Samurai, they quickly head back to warn everyone.
After telling Sorla that they had heard the Blizzard Samurai, she commands them to head inside so that they can regroup.
Uthaug, along with Boma and Sorla, calls over the ninja, showing them a green piece of the fabric worn by Lloyd.
Uthaug and Boma are looking for fish when the former accidentally slipped off the mountain. Boma tried to save him but was unable to pull him up. Fortunately, Cole came along and saved them.
Later, he told them he was trying to find the Traveler's Tree. Boma told him where it is, but discouraged him from going because of a beast named Krag. Despite their attempts to convince him, Cole bid them farewell and went towards the tree.
He, along with the other Ice Fishers, were frozen by Boreal.
Zane released the Never-Realm of its eternal winter and thaws everyone who had been frozen.
