Monster Blood IV is a children’s horror novel in the Goosebumps series by R.L. Stine, following Evan Ross as he faces another return of the dangerous Monster Blood. This time the familiar slime appears in a new blue form: instead of simply growing larger, it begins multiplying into strange creatures with sharp teeth. The story combines suspense, gross-out humor, and fast-paced supernatural trouble, as Evan is pulled back into a threat he thought he already understood. The novel focuses on fear, responsibility, and the panic of watching a small mistake become something uncontrollable, leaving Evan to figure out how far the new Monster Blood can spread before it is too late.
