Torrent Seal

The Torrent Seal is a key found in Wario: Master of Disguise. It is one of four keys found in the Ancient Waterworks, the others being the Floodgate Seal, Cataract Seal, and Waterfall Basin Seal. The purple treasure chest containing it is on the top floor of the ruins, hidden behind a fake wall that Genius Wario can see through. It is used to open a locked door with a picture of the key on it in the room directly below where the key is found.
