Wild-type unless proven otherwise with some crazy looking hatchlings. Mojaves have a very distinctive pattern along the sides; the rosettes (circles) look more like doughnuts or balloons. A good example of a mojave is a greenish/grey body with a yellow dorsal stripe. The colors are also off for a fire; they are typically very "clean," creamy looking, and have blushed brown heads.
