Like the Dzoonokwa, Bukwus is a wild creature of the woods. Described as a chief of the ghosts, he tempts travellers to eat his food, which transforms them into wild spirits like himself. The Bukwus dance is performed during the Tlasula.

The wood is cedar. The paint is red, black, and white.

Worn by participants in the Tseyka, these neck ring ornaments in the Burke Museum collection consist of a set of three carved and painted wooden plaques, representing the tail and flippers of a whale. There may have been a fourth piece representing the whale's head in the set. They were probably sewn to a rope-like ring of dyed cedar bark, perhaps 18 cm in diameter, which could be conceived of as the body of the whale. The bifurcate tail with a humanoid face for the joint hangs down the back of the wearer, while the two similarly decorated flippers stand out to the sides of the chest.
