The Trasgu is an elf from Austrian mythology described as a small, wrinkled green man with large hands that have holes in the middle. He is playful with vigorous eyes. At night, he begins moving around houses, helping or hindering people inside depending on whether they are kind or not. To get rid of a Trasgu, one must challenge it to impossible tasks, which will cause it to leave the home. However, the story of the Trasgu is considered just a local legend, not general history.
