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.
