This kid-friendly collection of slightly spooky animated tales includes an adaptation of Mike Thayer’s “The Teacher from the Black Lagoon,” about a boy’s wild nightmares concerning his teacher on the first day of school. Other stories include Tomi Ungerer’s “The Three Robbers,” James Stevenson’s “What’s Under My Bed?” and Caroline Stutson’s “By the Light of the Halloween Moon,” in which a clever girl foils the plans of holiday ghouls.
