Dan wants to know: What were the titles of the books written by Brainy Smurf?
A dear friend of Astro, Elizabeth, contributed the following: “The most important ones were “Quotations from Brainy Smurf” in an unspecified number of volumes. Brainy loves to quote from these volumes. He wrote various other books, like one from the episodes “Brainy Smurf, Friend to All the Animals,” and “Put-Upon Puppy”.
