I feel that in a way, that was put into the series to symbolize the way Campion re-started Efrafa in the books, and rebuilt it into a healthy, but still strong and active, warren. However, because of the new plot lines, they couldn't send Campion off to be the leader, so they had Moss go for it. I agree that they deserved some peace, though. But something tells me that those 3 big "bully" rabbits wouldn't have minded too much.
