A Walliper is a yak-like creature that lives in different parts of Ninjago. After Morro possessed Lloyd, the Ninja set off to Stiix by riding four Wallipers. At night, the group was ambushed by Wrayth, who turned Cole's Walliper into a ghost. Shortly after, the Ninja traveled up the Wailing Alps, where they found another Walliper. Jay and Kai briefly quarreled over whether it was a yak, goat, or cow.
While climbing up the Wailing Alps, the Ninja encountered a Walliper. Jay, however, believed it to be a goat, though after Kai claimed it was a yak, the Master of Lightning changed his opinion to it being a cow.
- The Walliper is based on the yak.
