This is the story of a little spider and a butterfly who have what some others in the forest consider 'physical adversities'. They meet and become the best of friends and discover they have unique abilities that allow them to help a friend in danger.
While it's a fairly short story, it has good guys and bad guys and gets to a nice moral at the end.
It's about spiders, but it's illustrated in a way that makes them more whimsical than threatening. A good bed-time story, perhaps.
