Iguana

Iguana is a species of lizard, one of the creatures fortunate enough to survive the Great War. They appear to have experienced no significant mutation as a result of the war, but their meat is sometimes irradiated. In New California, they are sometimes kept as pets, but there and elsewhere humans also use them as food. A common food item made of iguana is the iguana-on-a-stick. Another is iguana bits, popularized by a man known as Iguana Bob (even if his bits are sometimes supplemented with human meat).

Appearances in games
Iguanas appear in Fallout, Fallout 2, Fallout 3, Fallout Tactics, and Fallout: New Vegas. They are always dead and cooked, usually on a stick.
