Last month we saw a cross-stitch featuring all 151 of the original Pokémon. Redditor ninjazzy spent over 250 hours making something more tangible: tiny clay figurines of each Generation 1 monster. You can probably fit four of these in one Pokéball.
Each figurine sits on a penny, which is why ninjazzy calls them Pennymon. It also means ninjazzy literally has a penny for every original Pokémon.
