Bowser didn't look particularly concerned, even at the crossbowman hopping out behind him. He had his shell to protect him, after all (momentarily forgetting that half-orcs don't HAVE that). So what did Bowser do?

He threw his head back and laughed long and hard. "This is rich! YOU wanna steal from ME, and you only brought two of you? Do you have any idea who you're dealing with, you soft-boiled punks?"

Bowser suddenly stopped laughing, all traces of mirth gone from his ugly mug. "NOBODY steals from the Koopa King!" he roared, hurtling forward and swinging his battle axe like a big, nasty baseball bat.
