Once Rorschach was done finding hilarity in the idea, it was simple to tell why he'd been laughing at hearing that. "I just have a hard time picturing you as a kid of any species," he explained.

Bigby just sort of had the air of always being as world-weary and hard-bitten as he was at the present moment. Then again, so did Rorschach himself, but people didn't just spring forth fully-grown from the earth. (Most of the time.) Everyone came from somewhere, so it made sense a big bad wolf would have had to start off as a puppy at some point.
