Some people love to read books. They can't get enough of the (print) word. Others have a big appetite for making and eating food. Well, if you are both an (enthusiasm) reader and eater, you may want to take part in an edible book festival, you can have your book and eat it, too!
In such festivals, people create projects and present to judges. There are two rules: the project must be made of food, and it must be based a book. For example, someone might make the chocolate factory from Charlie and the Chocolate Factory with chocolate bars.
Sometimes, judges award prizes for the best projects like "Best Pun." A pun is a funny play on words that sound similar but have different (meaning), like tale and tail. A possible (win) for "Best Pun" might show Peter Rabbit, the character from The Tale of Peter
Rabbit, with a tail made of marshmallow fluff (棉花糖). (make) a pun, the project could be called "The Tail of Peter Rabbit", title punny enough to make the judges laugh!
Given the fun and often silly nature, it's not surprising that many of these festivals (hold) on April Fool's Day!
