Kubusmonster
Kubusmonster is a fictional creature commonly described in regional folklore and contemporary digital folklore as a cube-shaped entity. The name combines kubus, a word for cube in several European languages, with monster, to reflect its geometric form and folkloric status.
Accounts describe a perfect cube, typically one to two meters on each side, with smooth, unornamented faces
Traditionally tied to remote lakes, caves, or fog-shrouded forests, the kubusmonster is said to appear at night
In contemporary culture, the kubusmonster has appeared in speculative fiction, indie video games, and art installations
