“Come on it was just a tiny little joke, big bro...”
“Don't sell yourself short, you're not THAT little.”
“Very funny! Now get me out of the box!”
“It's your home now. Stop pouting and you'll find a new one in no time!”

Either a silly joke or Bunky's really gotten under his bro's skin this time. He looks to be in okay condition, but I would be careful about such a deal, might be either : full of fleas, very annoying, a magnet for troubles and demons, or some combination of these.
