Gila monsters are small reptiles found in all desert biomes. They are solitary creatures who only spawn one at a time. While carnivorous, they are less than half the size of a cat and therefore should not pose a threat to an adult dwarf. They do, however, possess a venomous bite which causes pain and swelling on the victim. They are natural swimmers and are able to path through water and breathe in it, should your map possess any.
Gila monsters are fairly standard as far as pets go, should the player choose to train them. They produce similar products to cats when butchered, and so can be used if the player wants some extra meat. They fare relatively well when used for egg production as they are one of the better egg-layers among desert creatures, laying between 2 to 12 eggs at a time. However, they are ultimately less productive than ostriches and several domesticated poultry.

Some dwarves like gila monsters for their venomous bite and their colouration.
