The family dog and cat are convinced the new rabbit is a vampire — one that drains the juice out of vegetables rather than blood. A 1979 chapter book, narrated by the dog, that outlived its own decade and kept turning up in classrooms long after.
Harry loves horrible things — slime, snakes, gross schemes — and his loyal best friend Doug narrates the chaos from Miss Mackle's class in Room 2B.
