In 1928, the Soviets sent out an expedition team to gather information about the Chuchuna near the Indigirka and Yana rivers. There they claimed to have found that Chuchuna were remarkably similar to the Mulen (Almas).
According to the native accounts from the nomadic Yakut and Tungus tribes, it is a well built, Neanderthal-like man wearing pelts as clothes and bearing a white patch of fur on its forearms. It is said to occasionally consume human flesh, unlike their close cousins, the Almastis. Some witnesses reported seeing a tail on the creature's corpse. It is described as being roughly six to seven feet tall.
