These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Funny: It was... pause... pause... pause... paws... pause... pause... A GHOST! (The pauses are actually written out and take up two whole pages before another two-page spread that just has "A GHOST!" across from a full-page illustration of the ghost. Which actually is somewhat scary in spite of this humor.)
Ear Worm: The songs, when you listen to them on the audio book versions.
Fridge Brilliance: Hank claims that the Coyotes' You No Take Candle way of speaking is its own separate language. It comes out the way it does because Hank is narrating the story, and his own understanding of Coyote is a bit limited, causing him to loose something in the translations.
Periphery Demographic: Erickson initially wrote the books for adults. He was a little surprised when he discovered that it was mostly kids that were the ones who were reading them. But he ran with it, and is still going strong today.
