Skeleton Hiccups by Margery Cuyler (2005)
Skeletons are a little less scary when they have the hiccups. This particular skeleton can't seem to shake them--not in the shower (nice fuzzy bat slippers!), not while brushing his teeth (woops! there goes the bottom jaw!), not while polishing his bones, carving a pumpkin, raking leaves, or even when playing baseball with his friend Ghost. Ghost, instead of Boo-ing! away his buddy's hiccups right away as we might expect, advises Skeleton to hold his breath and eat some sugar and drink water upside down. When he finally does Boo! it still doesn't work. But when Ghost finds a mirror and holds it up to Skeleton's face, he sees his reflection and screams in fright! The hiccups jump away, hic, hic, hic. While it's novel to see a skeleton eating sugar, drinking water, showering, etc., it may be tricky to find the right audience for this unusual picture book that's more about hiccups than Halloween.
