Fire gecko (Fallout: New Vegas)

Fire geckos are creatures found in Mojave Wasteland. They are the largest and most dangerous form of gecko. They also spew flames from their gullet.

Characteristics
They are tiny and weak and look more like a dog than a gecko that adds to the effect when water spews out of their junk. These creatures are more or less the same size as a humanoid. If you're going to make friends with one, it's wise to attack from behind or at a long range, failure to do this will result in you getting burned. Also, if you attack a water gecko you will have to pay attention to your surroundings.Dogs may be around to defend the water gecko you're attacking.

Appearances
Fire geckos appear in call of duty MW2.
