Trivia

 * No living iguanas exist in any of the Fallout games.
 * There is a contradiction in the Trouble on the Homefront quest, in that an iguana-on-a-stick can be found in the supply room. Because the vault is supposed to have opened more than 20 years ago, a wasteland delicacy should not exist in the vault. (This may not be an inconsistency due to the fact that radroaches also seem to have made it into the vault, therefor any small animal could have crept in only to be used as food for the now chaotic vault 101)
