Evan Ross is sick of being bullied by Conan Barber, the school bully who makes every day miserable. Hoping for a little revenge and a whole lot of fun, Evan reluctantly turns to the notorious Monster Blood again—despite all the chaos it has caused in the past. But this time, something’s different. Instead of the goo growing, Evan starts swelling up like a balloon, turning into a human skyscraper. As Evan gets bigger, his problems grow too—literally and metaphorically. Running from the authorities, losing control of his body, and struggling with his growing ego, Evan learns that being a giant comes with giant consequences. The finale crashes into a delightfully messy showdown that’s as absurd as it is satisfying.
Characters
Evan continues to be a classic R.L. Stine protagonist—curious, impulsive, and often in over his head. His best friend Andy adds comic relief and support, grounding the story even when Evan is towering above everyone. Conan, the bully, is more cartoonishly mean than complex, but he serves his role well in triggering the action. The charm lies in the familiar dynamics—Evan’s frustration, Andy’s sass, and Conan’s cruel confidence. It’s a fun trio that keeps the energy moving, even when the plot gets outlandish.
What Makes It a Great Read
What sets Monster Blood III apart is its physical comedy and exaggerated scenarios. R.L. Stine leans into the ridiculousness of the premise—imagine a 30-foot-tall middle schooler causing chaos during math class—and delivers a romp that blends sci-fi silliness with just enough horror to make your skin crawl. The pacing is snappy, the action never lets up, and the weird factor is delightfully high. Whether Evan’s stuck in a giant desk or squashing a bully’s ego, the book delivers laugh-out-loud moments and “what if” thrills in equal measure.
Literary Merit
While not as chilling as other Goosebumps tales, Monster Blood III succeeds by embracing the absurd. It taps into preteen fantasies and fears—wanting to be powerful, feeling out of control, getting justice on a bully—with wild imagination and gooey glee. Stine’s prose remains simple yet effective, his cliffhangers on point, and his ability to blend gross-out horror with humor still unmatched. For fans of the series, this third helping of Monster Blood is a messy, manic, monstrously entertaining ride.
