As everyone heads back to the ship, Mildred the crow comes to meet them to find out what happened. Arthur flies back with her once he de-cheeses his wings.
Arthur gives Grandfather a big hug once he's on board the ship; then they start cocoa for everyone.
But then the Squeakers show up to arrest everyone. Willbury says he'll return from retirement to pursue it in court, and further, he presents Herbert as a key witness to the poisoning case that happened so many years ago.
The police chief is embarrassed to learn all this, now that Willbury has evidence that Snatcher has been breaking all kinds of laws. The police all depart in a hurry.
Willbury tells Grandfather that it should be safe for him to return to living aboveground.
