Region of origin: The Baltic Sea, Germany
A nautical subcategory of kobold or brownie, a klabautermann would take up residence on a ship and be a generally pleasant albeit unseen addition to the crew; he would assist with sailors’ duties, sing songs to lighten the mood and help rescue crew that had fallen overboard. When seen, they were said to appear as small men in yellow rain gear, but they only made themselves visible on a voyage if the ship was doomed to go down that trip. In more modern usage, the klabautermann has become something more of a seafaring gremlin, being blamed for things that go wrong on the ship.
