This was done by Merlin Missingham over at DHS Comix! Superb design!
Merlin also did this amazing picture of Bonny, capturing all of her aggresive sassiness. And while you’re at it, go check out DHS Comix, as well!
LooeyQ gave Filbert this cameo in his comic, Mad Dog! If you scroll to the right and down, you can see him in the middle of the blast!
KarToon12 who does a wonderful comic called Jamie Jupiter, did a fanart video of her drawing Rusty!
