One of the few inventions by Leonard of Quirm that made it to the outside world. This particular one could be found in the Mended Drum and was a sort of 3-ton, water-driven trivia game. It was removed after Captain Carrot added questions like "Where were you the night of the 17th of Grune?" or "Who did the robbery of the jewellery on Filigree Street?", causing a large part of the clientéle to get arrested.
