The Myth

Ugjuknarpak is a gigantic, mouse-like monster from Inuit folklore in Alaska. It was said to inhabit an island in a long, narrow lake near the source of the Colville River. Although resembling an ordinary field mouse, it possessed impenetrably thick skin that could withstand even the largest harpoons, knives, and arrows. Its long, prehensile tail could coil around its prey, making it a terrifying predator.

The Inuit travelling by umiaqs to trade with the people of Point Barrow feared Ugjuknarpak greatly. Any noise near its island could alert the monster, which would rush at passing boats, capsize them with its powerful tail, and kill and devour their occupants. Despite this danger, travellers had to journey downriver to obtain blubber and return before winter froze the river, when caribou hunting became essential. In one tragic incident, a girl survived because her father placed her in a quieter boat ahead of the main fleet. A dog’s snarl alerted Ugjuknarpak, which attacked the other boats and killed her parents and brothers.

The girl eventually married and had a son, whom she named Kugshavak, meaning “Woodpecker.” She deliberately told him that he would never be strong enough to avenge his murdered relatives, knowing that this challenge would inspire him to prove her wrong. He was later joined by his brother Hagáneq, meaning “Fellow,” whose hands resembled the flippers of a bearded seal. Together, the brothers grew into powerful heroes and eventually set out to kill the monster.

Approaching the island silently, the brothers discovered Ugjuknarpak waking with jaws so enormous that they could see the dawn through its open mouth. They lured it towards a riverside plain, dodging its attacks while searching for a weakness. Eventually, they noticed a wrinkled patch of skin on its neck. Armed with flint knives mounted on long spears, they repeatedly stabbed this vulnerable spot until the monster collapsed and died. The brothers severed its head and displayed it at Ivnaq, where passing travellers could see the remains of the once-terrifying beast. Although the head eventually decayed, its enormous size, long fangs, and gristly mouse-like snout continued to frighten travellers, who passed it in whispers and restrained their dogs to prevent them from making noise.

Uiluruyak

Tradition: American Mythology
Alternative Names: Wi’-lû-ghó-yûk, Sea Shrew
Category: Rat


The Myth

The Uiluruyak is a small, mouse-like creature associated with the sea ice of Alaska in Yupik folklore. Although the name has been identified with the meadow jumping mouse (Zapus hudsonius), the explorer Edward William Nelson described it as a sea shrew. Hunters are said to encounter it on the frozen sea.

When the Uiluruyak sees a person, it darts forward with incredible speed, pierces the sole of their boot, and crawls beneath their clothes. If the person remains completely motionless, the creature eventually leaves through the same hole it entered. Those who endure the encounter without moving are said to become successful hunters.

However, even the slightest movement can prove fatal. The Uiluruyak is believed to burrow into the victim’s flesh, pierce their heart, and kill them. For this reason, hunters are warned to remain perfectly still if they encounter a mouse on the sea ice, in case it is the dangerous Uiluruyak.
