A bulbous body floats toward you. It has a central, unblinking eye, and a large maw filled with daggerlike teeth. Smaller eyes, attached to wriggling stalks, sprout from the top of the orb-like body.

The gas spore is a highly specialized form of plant life originally created by ancient beholder mages. Since then, these prolific creatures have spread far and wide.

While a gas spore resembles a beholder in appearance, it is in fact a form of fungus. The creature is hollow, filled with a large volume of spores under terrific pressure.

A gas spore is typically about 8 feet across but weighs only 50 pounds.
