Story
''Somewhere atop of a serene field of pure snow is a creature that keeps a wary eye on the world. This legendary Pet only appears when the mountains face dark and sinister threats. By throwing a barrage of snowballs and causing the mountains to shake with a thunderous roar, malicious foes are defeated with ease. Thundersnow Yeti has a soft side as well, as legends say it provides the beautiful snowfalls during the festive winter holidays.''

Trivia

 * Mystical animal mural.png the murals found in the City of the Millennial Tree, Emerald Golem, alongside the other mystical animal Pets, can be found with a question mark in the center. It is unclear what the question mark entails, as it could be a fusion of all the Pets together or an entirely new entity, or any other explanation.
 * This seems to be retconned however, as during the The Truth of the City story, as this question mark was replaced by instead.
 * Thundersnow Yeti is currently the only Pet who has the ability to freeze the Energy Bar completely. This uniqueness can also result in the Cookie to still have the ability to run even with 0 Energy, so long as they are running while Thundersnow Yeti is activating its skill.
 * Uniquely, unlike all the other mystical animal Pets whom so far had no story appearances, Thundersnow Yeti appears in the Sands of Yogurca story, being the catalyst for the blizzard in Yogurca.
 * A beta design for Thundersnow Yeti was found in the files for Cookie Run: OvenBreak and CookieWars long before its release as well. The final design defined its stripes more, and it was redrawn more cleanly.
 * Thundersnow Yeti is the mascot of the Glacier region in the Grand Champions League and is shown on the region's banner.
 * Thundersnow Yeti's internal name is "pet0119".
