The books are compilations of individual comic strips, and at the end of each there are several, outdoorsy activity projects.
I am recommending these, because I found I was being introduced to a little boy, and his neighborhood buddies, who I liked; kids that said funny things, noticed squishy surfaces, and seemed to be content in who they were. I also liked the author, who created a world on a drawing board that he made available to the public in a daily feast of a few pictures and bubbles with words. One of my favorite excerpts, from Snug Harbor Stories, is when the characters take time to watch a web being built.
