So I managed to get more Pokémon done! Thank goodness for the holidays.
Here's Chespin and co. I based Chespin off of a Chipmunk/Chestnut.
Quilladin was based on a Hedgehog/Chestnut/Armadillo.
I thought those animals really accentuated the long arms and claws that Chesnaught has plus that characteristic armour. There was no way I was going to make it some hot, anthro furry with knight's armour. I imagine a lot of plant matter would grow on the shell and fur of Chesnaught (like on sloths) but I couldn't be bothered adding that in.
