----- Time to copy-paste a lore dump from the portrait of Chip I posted previously, since underwear art actually gets views...
Despite not drawing him in many years, or drawing him much when I was actively drawing him, Chip is a character I had some plans for. He is little Aylen's father, and doing the "single father" thing after his partner (Aylen's as-yet unnamed mother) was killed in a car crash at some point a few months after Aylen's birth.
I don't recall if I ever mentioned that particularly morbid detail anywhere in the past, but that's been a major part of his and Aylen's backstory pretty much since I decided to make the (at the time) two one-off characters into a family--especially with Aylen bearing a much stronger resemblance to other raccoon characters of mine, such as Meryl, Mia, and Reed, than she does Chip.
As for Chip, his coloration would suggest that he's related to Gretchen and Rochelle, which is something I've sort of implied but never outright stated anywhere, although I haven't determined 100% what the relation is (I am thinking that Rochelle is likely Chip's sister, while Gretchen is his cousin).
