As the unnamed narrator looks on, a skeleton, a ghost, a vampire, a werewolf, witches, goblins, gremlins, a devil and a mummy pass by. The monsters are in fact children dressed up in Halloween costumes, but Brett's pictures are deliciously scary. They strike a perfect balance between the children's costumes and their imaginary personae, drawing readers into a make-believe world. When the children go indoors, the narrator and his friends - a gang of adventurous pussy cats - stalk the streets to prowl till dawn. Luminescent colors glow eerily in the darkened neighborhood; this holiday poem possesses all the atmosphere of the spookiest Halloween.
