Kletnik

In Slavic mythology, a spirit living in a storage cage is a brownie's assistant. Keeper of the cage and various utility rooms. He is very small in height, with long hair and beard, his clothes are in flour. During the day he sleeps off, and at night he goes out to play pranks. Arranges an inspection of things, shifts them from place to place.

Western Ukrainians have a hundred-year-old, which is akin to a cage, it protects the hundred-year-old, brings prosperity.
