Punchy... always Punchy.
But then again, I've never felt attached to Lucky whatsoever. He creeps me out too much, and not in a fun way like my arch-nemesis Bubbles, or in a nostalgic way like Tabby, or in an -OMG- way like Hopkins (the first time you see the back of his head and realize what's hiding there in plain sight).
Punchy has historically always been one of my favorite AC villagers, dating back to my second town in AC (same applies to Bob). I've had him at some point in every game since then, not by searching specifically for him but just by pure luck (like Rosie).
Still, I can appreciate Lucky and his design! It's certainly unique!
