Swampires are enemies in Paper Mario: The Thousand-Year Door. These are the toughest forms of Swoopers. These guys are only found in the deepest section of the Pit of 100 Trials. These guys, like their previous versions attack and try and suck out blood. They attack like normal Swoopers, so they don't repeatedly suck out six hit points as if they were a Swoopula. These enemies also have a large number of hit points, so these are some of the most formidable foes in all of the game.
