You don't often see cartoon characters get implants but that's exactly what I suspect is going on here. But what kind of implants are we dealing with? Those are not your garden variety big fake boobs. (What kind of expression is "garden variety?" I know WHEN to use it but I never really bothered to research the etymology.) Arsen thinks they're made of jello, I say it's some kind of custard pie filling. What say you, precious reader?
