Shadow mini-racer on his bike looks just about like the larger version, only he is totally non-pose-able. The bike also will not stand on its own. The tires do have traction though, and you can still spot the Shadow symbol on the gas tank. Notice that they detailed/painted the bottoms of his shoes, which is quite a nice touch, especially on something this small. 

As for the box, the bubble cards for these are the same, except for the name plate on the front. The backs always have this shot of Sonic in his car, and the logo. The shiny dot you see on the front says "Safety Tested" with a check mark. Notice the absence of any "Toys R Us" labeling, the dot merely says "From the Hit Game" All of the figures are packed slightly titlted downward for some reason, perhaps to expose the top better. The bubble and card are pretty large, likely as anti-theft, vs such a small item inside. A second clear inner shell keeps the figure in place inside.
