It's Halloween, and Splat is determined to be the scariest cat in the class. Unfortunately he's just too much of a scaredy-cat. He's afraid of a little spider, and everyone says his costume looks more silly than scary. And when Mrs. Wimpydimple tells a ghost story in the dark, Splat gets so frightened that he tips over his jack-o'-lantern. But when the lights go back on, the entire class is scared silly by a small, black, furry creature with a big pumpkin head. Whooooo can it be?
