Brazil made more than just a pin, they also created this PVC Sonic figure. He's quite all right looking for the time, with thought-out spikes and mostly proportional hands and shoes. This was made in 1994, but because its from Brazil, it's not very easy to get as items didn't seem to leave the country that often to be collected.
In Brazil, they didn't stop at just Sonic with the PVCs. Here, they tried their hand at Robotnick (AoStH style) and Tails. You'll notice the mis-coloring on Tails right away, his glove cuffs were never supposed to be blue.
His brownish color was likely thought to be correct at the time, due to botched up stock art and Archie Comics as well as SatAm Sonic mis-coloring him this way for years in the USA. Robotnicks eyes also appear to have white in them, instead of red. The other noticible difference figre-wise on Tails is that he's shown with his tails arranged vertically, where other pvcs usually show them side by side. It is likely all 3 figures appeared in Brazil stores at the same time in the 1990s. The back of the Robotnick is stamped "TM & (C) SEGA 1994". But what company produced them there?
