AH! I knew these would surface some day. These aren't even an official SS product. I have seen these figures in those cheap dollar stores that exclusively sell bootlegged products. You can tell the way that the word "Stickers" is written.
They must be random AM characters that popped up in a coloring book. And the bootlegger involved picked them out because they didn't know the difference.
Surely, you have seen the old bootlegged Taiwanese/ Hong Kong stickers before. These of course are examples of well made ones (I've seen some horrible ones, including a Caucasian version of Chef from South Park and a book of Bootlegged Chicken Little stickers called "Sea Life")
