Character Analysis
What's the deal with those birds who schlep Gertrude around for two full weeks at the end of the story, despite any damage to their beaks? Like Lolla-Lee-Lou, they're not really fleshed out and are more of a symbol. They're there to say, "SEE what kind of harm you do not just to yourself but to the people around you when you're selfish and vain? You don't make decisions in a vacuum, toots."
Yep, even in this very short, much simpler parable, Seuss is still concerned with the effect the actions of the few have on the lives of the many.
