Description
A thunderherder is a cousin to the purple worm which travels in vast herds just a few feet under the ground in desert regions. The thunderherder is not aggressive, but causes incidental earth tremors and a terrible trumpeting as it stampedes underground, causing a great deal of confusion, knocking over tents, and panicking pack animals.
