A-Mi-Cook

In Inuit mythology, a sea monster that lives in the waters of the Bering Strait around the city of St. Michael, washing Alaska.

Ä-mi’-kuk is the original spelling of the name.

He attacks kayakers who have sailed far from the shore, and drags them to the bottom with the help of tentacles. It is covered with slime and is able to move easily both under water and ice, and underground (when it breaks through tunnels, lake water goes into the sea, when it returns, the water also returns). ​‌​​​‌ ​​‌‌‌​ ​​‌​‌​ ​‌​​​‌ ​​‌​‌‌ ​​‌‌‌‌ ​‌​​‌‌ ​‌​‌​‌​ ​‌‌​‌‌​ ​‌‌‌​‌‌ ​​‌‌‌‌

The creature has four long tentacles or (in another version) tenacious human arms and legs (or four arms).
