Golden gecko (Fallout: New Vegas)

Golden geckos are creatures found in Mojave Wasteland. They are like the other geckos of the region, but with shiny golden scales.

Characteristics
Golden Geckos have been affected by high levels of radiation, and as such, when they attack you, you will accumulate between 14 and 20 rads. Upon killing a Golden Gecko, you can find a Golden Gecko Hide, Golden Gecko Egg, and Golden Gecko meat, which can all be sold for a higher price than its normal Gecko counterparts. There are a large number of Golden Geckos around and in the tunnel near Vault 34. They are smaller than humans runs very fast and open there mouths wide while running in for an attack

Appearances
Golden geckos appear in Fallout: New Vegas.
