Flooded rooms allow for unique interactions with some Items such as Jacob's Ladder and enemies. Sometime rooms can be "flooded" with water, blood, or lava depending on the Chapter.

Isaac cannot leave a Room with enemies until they are all killed or until a door is opened with an explosion. Many Rooms also contain various pickups, chests, items, and obstacles. These Rooms typically contain enemies and may drop a pickup or chest after all enemies are killed. Normal Rooms make up the majority of the Rooms on a floor.
