There is a series I read as a teenager, the Xanth series. The author, Piers Anthony, has been pumping out a book a year for the last 45 years, so there are a lot of them. I read the first 15ish for AR point in school back in the day. It's not exactly the height of literature, but they're pretty fun for children/teen fantasy books. The thing that really sets the series apart is that Piers fills his fantasy world of Xanth to the brim with magic plants and creatures based on puns. In one of the earlier books, there is a tree that grows fruits that look like babies. An Infantree. And when approached, the fruits drop and the babies start marching around and attacking the threat, like an infantry. It's one of the most memorable puns to me.
Oh for sure. He often used puns that his fans gave him in fanmail too. He'd take their ideas and try to fit them somewhere into the story. He credited them in his books all the time.
