i know im kinda late on this but there is nothing special about that iguana posted on kingsnake. i saw the ad and i laughed when i read it. there are a ton of iggs that look like that. when they get older the pattern will just turn a bronze color when he is older. and they call it a "cryptic" pattern. people are idiots and will try to market anything these days lol.
i feel bad for the stupid SOB that buys that igg lol. i dont like any of the color morphs that are out for iggs. they may look cool but they arent worth the money. i have a regular igg and when mine is fired up he has a decent amount of red in him.
