Kybucks were ungulates native to the Woolwarricca prairies of Kashyyyk, and similar in appearance to the Tauntauns of Hoth. Their swift speed, along with the cover of their natural environment, allowed them to be able to run from predators. Kybucks could run at up to 90 kilometers per hour. Males had short horns sitting atop their head. There were many different breeds of kybucks, often identifiable by relative size and form of their horns. Kybucks mated for life. They raised an annual litter of two or three foals in rearing grounds protected by a barb thicket. Kybucks tended to flee from enemies when alone, but if a foe threatened a kybuck's offspring, the parents would fight to defend them. Kybucks attacked using leaping kicks and horned head-butts to fight off enemies. Judging by the way Yoda spoke to his kybuck, these creatures appeared to be quite intelligent.
