Some fluffy lived longer than expected. Some due to survival instinct, luck or just noone cared. This old one lived his life, seeing friends and mates grow old and died and now finally his turn as he calmly walks into an old, once playground by human kids after the war, with thick bushes, tress and old metal…now act as final resting place of old fluffies like him. Rest well old one, you deserved it.
Not gonna lie I thought this was the same fluffy too- the trees in the background lining up with where the little apple tree was initially probably helped to sell the illusion. It would explain all the mossy growths and such on his fluff too.
I also like the details of how his legs are all bent and clearly only barely holding him up anymore, even without the gray and wrinkled muzzle its obvious this is a fluffy that is old and about to pass away of natural causes- a real rarity.
