Bowser The Hound in "The Surprise Of Blacky The Crow"

Blacky waited a few minutes, then repeated his cry. He did this three times and had just made up his mind that there was nobody inside that little house when a head appeared in the doorway. Blacky was so surprised that he nearly fell from his perch.

"As I live," he muttered, "that is Bowser the Hound! It certainly is.
Now what is he doing way over here? I've never known him to go so far from home before."
