I found Carnage yesterday at Walmart. Combined with finding the Sentry, I've now found 2 out of 3 things Neal has (not Marvel Universe Wave 11 yet), and that ain't bad. In fact that's a borderline miracle.
Carnage is okay. Couple things though, like Neal said the articulation could have been better. Also the black goo lattice deco is kinda interrupted on the figure and doesn't extend onto the ball joint part of the hips and looks kinda weird as a result. Additionally the teeth are painted in black, for some reason, even though in the 3 pictures of Carnage on the package they are all white.
So basically 5 minutes with a paint brush will fix most of this, and then he's pretty good.
