I have just recently received "Swamp Patrol" Zartan as a gift from a friend of mine. He of course is a very nice figure, but I'm a bit disappointed that his skin does not change color in the sunlight. However, with two other Zartan figures (One out that comes with one mask, back pack and a rifle that does change color, the other coming in the next Cobra 5 pack that looks exactly like the Zartan I own except without the swamp ski) My question is my Zartan faulty? Or is the one I have not supposed to change color? And what of the Zartan coming out in the 5 pack, is he supposed to change color?
