It’s no trick: Fans of the hit PBS Kids television show *The Cat in the Hat Knows a Lot About That!* are in for a treat this Halloween with this book featuring two holiday stories. In *Trick-or-Treat!* , the Cat and kids visit with a spider monkey, a coconut crab, and a fruit bat to see some amazing tricks and to sample some exotic healthy treats. And in *Aye-Aye!* , when Sally and Nick need help making scary Halloween masks, the Cat knows just what to do. He takes them to visit an aye-aye—a creepy-looking creature whose frightening looks are perfectly adapted for his environment. All in all, this is a Halloween treat sure to make parents, kids—and dentists—smile!
