The Căpcăun is a creature in Romanian folklore depicted as an ogre that kidnaps children or young ladies, especially princesses. It represents evil and has characteristics like a dog's head, sometimes with extra eyes or legs, and is known for eating humans. Many heroes have attempted to rescue fair maidens from the Căpcăun but often fail due to its evil tricks, as it lives alone in a den giving off a stench of death and readily attacks anyone who passes by.
