Just when you think you've seen all the meal toys, another set pops up! Here is a (quite old) set from Burger King in the UK. These appeared in 1993, so BK really was getting a jump on things here. First, you can see a 'spring open' container from the end of the level, complete with 3D Sonic on top. Inside, you can see the little walrus which you release in the games. The sculpt of the Sonic topper is actually really nice. He's proportional, well painted, and quite appropriate. It's too bad more meal toys can't say the same.
Next up is Tails. He suffers from a somewhat poor sculpt and 'oval eyes' which they did not really pay attention to the shape of. Likely due to age, his white parts have gone pinkish further detracting from the figure. Why is there a hole in him? For a rip-cord. The bit on the side likely held his tails which could be spun by pulling the cord in his front. The Eggman is not a ball, but rather a gyroscope type toy which wobbles when the cord is pulled. It's tacked up here, because he won't sit up otherwise. The 2nd Sonic of the set is a wheel launcher. Pull the cord to launch 'spinning Sonic' from his Marble-Zone like base starting area and he'll roll along the floor.
With a fair amount of interactivity and "Gizmo Factor" this is an interesting early set to collect.
