"In Sanchez’s illustrations, green and yellow swirls pop against the muted gloom of the house; readers will positively smell the noxious fumes. From the opening lines—"Tonight is a big stinkin’ deal"—all the way through to the conclusion, this tale will have readers in stitches with its goofy wordplay."—Kirkus Reviews"Hold onto your butts or they might get haunted!… With plenty of onomatopoeia and flatulent green clouds to animate the eerie chase that ensues, this haunted-butt mystery will entrance fans of ghosts and gas jokes alike."—Booklist
