Yep, "The Sub" for short. We tried different names for him but this one stuck. He came to us overweight and with fairly bad edema, shaped sort of like a submarine. I guess. And he's yellow. And it's a reference to a Beatles song/movie and slang for a marijuana cigarette.
He's kind of got more of a Hulk vibe going but there have been other Mitsio breeders in the US named Hulk in recent years so we wanted to avoid that.
Do you care to suggest a better alternative?
