Ever since I rediscovered Muttski through the reboot of the Archie comics (and thanks to a few friends) I've begun to see Casey and Ben hanging out together as best buddies.
Don't know how, don't know why. Don't care. They're cute together, so they're friends.
Ben Muttski to Archie / Archie Sonic TH Comics
Casey to :iconisaacs-collar:
Also, PS, Casey y ur hair so weird.
