An eccentric babysitter has a knack for telling stories that are eerily well suited to her young charges. When Carolina Giddle moves into the Blatchford Arms, no one knows what to make of her sequin-sprinkled sneakers and her trinket-crusted car. But the parents are happy there’s a new babysitter around, and Carolina seems to have an uncanny ability to calm the most rambunctious child with her ghostly stories. Armed with unusual snacks (bone-shaped peppermints, granghoula bars and Rumpelstiltskin sandwiches), candles to set the mood, and her trusty sidekick — a tarantula named Chiquita, Carolina entertains the children with some good old-fashioned storytelling and, at the end, a great Halloween party. Governor General’s Award winner Glen Huser brings his quirky sense of humor and horror to some time-honored motifs. The artistic Lubinitsky girls find out that artists must be wary of the power of their own creations. Holy terror Angelo Bellini discovers that no one can throw a tantrum like a double-crossed pirate. The Hooper kids, including UFO junkie Benjamin, learn about some eerie goings-on in the New Mexico desert.

And Dwight and Dwayne Fergus, two would-be Freddy Kruegers, finally meet their match in Carolina, and her story of the footless skeleton. As for Carolina Giddle herself, it turns out that she has a timeworn connection to the Blatchford Arms, and to the ghost who still haunts the building — especially its old-fashioned elevator.
