Iggy was a juvenile Iguanodon to which Eric Kirby had several encounters with. Scared by a nearby Velociraptor, Iggy actually ended up saving Eric’s life. Finding its way into the Embryonics compound, Iggy got its foot attached to a book, to which Eric was able to identify it with later.
Finding its way back to its herd in a small valley, Eric attached an electrical generator in an attempt to save the herd from being kept captive by the Raptors by leading an attack charge. The plan failed, and Iggy was eventually surrounded by some of the Raptors and killed.
