Went looking for any new knockoff dinosaurs again today and noticed that while not new moulds, there are now "sets" that contain the T-Rex and Indominous Rex with new, unique printing. I-Rex is still white but its colors are greys and browns, not unlike camouflage. The T-Rex base color is a weird soft lime-green with black markings and orange around the eyes. They don't look like they're by the same group that does the other ones though so who knows how the quality is.
Edit: Also the I-Rex has what appears to be brick-built spikes on its back!?
