The Igua Norns are a payment-required breed for Creatures 2, bundled as part of the world Montu. Igua Norns got their name from their lizard-like eyes and Iguana patterned skin. They occupy norn breed slot X. The Igua sprites are based on the original C2 Emerald Norn, and use a modified Canny genome.
A C3/DS conversion has been considered but never fully implemented since the breed is not free.
