Slurks are thought to be descendants of a failed dwarven attempt to domesticate and breed large subterranean frogs as food and labor animals. Despite this apparent failure, slurks are often befriended by others who live underground. The sticky frog-beasts have proven extremely desirable to kobolds, who now domesticate and train slurks as powerful mounts and guardians. While other creatures, particularly boggards, sometimes train slurks to serve as guardians, kobolds remain those who use these creatures the most. A kobold mounted on a slurk will often hide in the upper ledges of a cave, using the advantages of height and surprise to harry foes with ranged attacks. Kobold riders also take advantage of the slurk's ability to climb, and charge at their enemies from the walls of a cavern.
