Monster Blood III is the twenty-ninth book in the original Goosebumps book series. It was first published in 1995.

The illustration on the cover shows Evan Ross's large legs on the playground with spilled Monster Blood nearby.


Evan's annoying little cousin, Kermit Majors, is getting on his nerves. Kermit is always conducting strange experiments, that usually get Evan in trouble. Andy decides to help Evan strike back by sticking a bit of Monster Blood in one of Kermit's mixtures. The mixture grows larger but then bursts, flying around the room. Evan accidentally swallows some and soon begins to grow bigger and bigger, almost ending up trapped in the basement. He narrowly escapes and stops growing, when he is several stories high. His clothes also grow with him, because they are splashed with some of the monster blood.

At first, he gets children's kites out of trees and they call Evan "Super Evan", but he crushes a car. After more unintentional accidents, the police and fire department hound the enormous Evan, believing he is an alien. Fortunately, Kermit quickly invents a compound which will make him shrink. Evan drinks the formula and (after a few unwanted results such as turning blue, getting hiccups and growing feathers), he shrinks, but shrinks too much and by midnight, he finds himself only a few inches tall. Using his dog Trigger, he makes his way to his father to tell him of his problem.
