Another single 'space figure'.
What's up with these space suit figures? The box-back doesn't elaborate & it doesn't have a special title. Like the Tails at the top of this page, the Knuckles here comes with a badnick figure, and it's Crabmeat. Ironically, this robot is actually pretty menacing looking with its highly skeletal face making it more fearsome to look at than it particularly acted in the show.
What's different about this one though? Notice that 'single Tails' up there had a different colored suit than the suit in the 3-pack...but this one has the exact same white/red suit.

Why? Why not make the Knuckles single pack also a variant suit color...if they *already* did it for the Tails? That way at least you'd have different figures and not "be buying the same thing over and over just to get the accessory" which everyone has known about and hated for years. It also seems uncoordinated to at least try to match the singles figures into a set.
The duplicate nature of the suit vs the 3pack, it not matching the Tails from the set, no explanation, no matching art (normal show Knuckles is on the back) and no reports of where this was sold make this figure pack a Tomy mystery.
