The Yeti are white-furred creatures with pine green skin and egg-shaped bodies. They are mostly covered in fur, except on their feet, arms and mouth. Their legs are extremely stubby with two toes and black claws, and their arms are surprisingly small with only two digits. The top of their heads and their faces are covered in fuzzy fur, except for their mouths which have pink lips and sharp teeth.
Yetis are show to come in different sizes. The smallest (which appear to be children) are a few meters taller than Sonic the Hedgehog, while the biggest are two-three times larger than that.
Characteristics and culture
The smallest Yetis' only interest seems to be sleeping, and when awoken, they tend to wail. However, the largest Yetis are short-tempered and quite aggressive, charging into any intruders they may spot.
Powers and abilities
The Yetis have surprisingly soft bodies that can bounce back whatever physical blows they may receive.
In gameplay, the Yeti serve as gimmicks/obstacles to the player. Whenever Sonic collides with a Yeti, it bounces him back, similar to a Bumper. This can both be an advantage or an issue to the player, as Sonic can both bounce between Yetis for an easier route (if done correctly) or get unintentionally pushed off the Zone's narrow roads.
Smaller Yetis are unmovable and stationary creatures that sleep peacefully until Sonic collides with them. However, larger Yetis will become enraged and turn red when they spot Sonic and will actively pursue him to bounce him off the road. After colliding with him though, these large Yetis will bounce back and disappear from sight.
In Sonic Runners, the Yeti appears as a Rare Speed Type buddy which triggers the Cyan Laser effect for every certain number of combos. There is also a variant buddy of the Yeti called the "Christmas Yeti" which is a Power Type and boosts the bonus score when combos are performed. Both buddies could only be obtained during the 2015 "Christmas Event."
