Goosebumps. Monster Blood

Something scary is happening in GOOSEBUMPS HORRORLAND, the all-new, all-terrifying series by R. L. Stine. Just how scary? You'll never know unless you crack open this classic prequel! Evan visits an eerie old toy store and buys a dusty can of Monster Blood. But then he notices something weird about the slimy green ooze. It keeps growing. And growing. And growing.
