Thundersnow Yeti

Thundersnow Yeti is a Legendary Pet released on August 13th, 2019. It has the ability to temporarily freeze the Energy Bar, preventing Energy from decaying until it finishes. While this is active, it will also throw snowballs to destroy obstacles and create Snowball Jellies.

Thundersnow Yeti debuted in Sands of Yogurca with the Season 4 update, and was shown in story cutscenes and on the main menu before its release. It will be received at the end of the week if the player has reached at least Diamond V in Sands of Yogurca, and it can also be bought at the Breakout Shop.

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.''

Skill
Freezes the Energy Bar at certain intervals. While the Energy Bar is frozen, a barrage of snowballs destroys obstacles and creates Snowball Jellies. Level Up for more snowballs thrown.

Strategy
Thundersnow Yeti is one of the best Legendary Pets, if not the best. Its skill can make a run last much longer, which is always valuable as it allows the abilities of the Cookie and Treasures to activate more. It is a good choice for Trophy Race or Breakout Mode as long as its Cookie partner is not too reliant on their Combi Pet.

When the Energy Bar is frozen, the Cookie is not invincible, and can still lose Energy from falling into pits or colliding with obstacles that the snowballs missed, so it cannot be relied on to avoid injury. Due to the way its skill works, Thundersnow Yeti is more effective in stages with faster Energy drain compared to healing and reviving Pets.

Cookies with higher Energy will naturally be able to activate its skill more and extend their runs even longer. Fire Spirit Cookie is an interesting partner, since his skill similarly stops Energy drain when active. When playing with this pair, try to activate Fire Spirit Cookie's skill when the Yeti's skill is not active.

Trivia

 * Thundersnow Yeti appears in a mural in the background of Golden Cradle, the sixth stage of City of the Millennial Tree, along with the three other previously released Legendary Pets. This foreshadowing had been in the game since April 28th, 2018, the first day of the Season 3 update.
 * This is consistent with Alchemist Cookie recognizing Thundersnow Yeti and referring to it as a well-known legend.
 * 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.
