About this book
Back in Room 3B, Doug narrates as his best friend Harry turns a rainy-day playground into a hunt for mysterious “mud gremlins.” When messy footprints and odd clues cause a stir, the class uses observation and teamwork to figure out what’s really going on. Short chapters, school humor, and familiar friend dynamics make this an inviting read for newly independent readers. Perfect for kids who like classroom capers and light mysteries without anything too scary.
Setting: an elementary school classroom and muddy playground (Room 3B)
