Charlie and his little sister Lola are headed to the library, where Lola can't wait to once again check out her favorite book, Beetles, Bugs and Butterflies. She feels that this is the best book in the world and loves it especially because it makes her laugh. Once at the library, she finds that it's not on the shelf and she's very upset. It's up to Charlie not only to quiet her down, but also to see if he can't find another book that she'll enjoy just as much.
