Query: Great spook story

Like most 4 year olds, my son loves scary stories. Just as typically, he freaks out if the scary stories turn out to be, well, scary. This is a perfect scary-but-not-really story that's been our number one bedtime read for several months now. The cumulative (every page repeats the previous page and adds a line) poetic structure does a lot to hold his interest, as do the wonderfully goofy pictures. Lots of fun.
