Random Dungeon, Room 6

Another large chamber roughly 20 ft wide but 40 ft long. The ceiling in the southern half of the room looks as if it partially collapsed, as several feet of rock are shattered on the ground and the ceiling extends about 5 ft higher.

Hiding in the rubble is a giant snake (50% chance for either a constrictor or poisonous snake). If not discovered it will strike with surprise.
