A Dark Tileoid is an enemy that appears in Super Paper Mario.
Dark Tileoids can only be found in the Flopside Pit of 100 Trials. They are also the strongest of all of the Tileoids. Like with the other Tileoids, Dark Tileoids are found moving across the floors, walls, and ceilings. Anyone will take damage if they come into contact with a Dark Tileoid. Dark Tileoids are a lot more resiliant than the regular Tileoids.
