Wendy and her younger brother Marty are separated from their parents after a freak accident involving their trailer and find themselves at a strange summer camp called King Jellyjam’s Sports Camp. At first, it’s all about races, games, and winning medals—but something feels off. The camp counselors are overly strict, the other kids are acting weird, and there’s a strange stench in the air. As campers who lose start disappearing, Wendy sets out to discover what’s really happening at Camp Jellyjam—and the truth is slimy, monstrous, and far more horrifying than she ever imagined.
Characters Who Must Outrun the Fear
Wendy is resourceful, determined, and one of the more active heroines in the Goosebumps universe. Her brother Marty provides a mix of humor and realism with his relatable kid behavior. The counselors, all eerily obsessed with the camp’s slogan—“Only the best!”—are unsettlingly robotic. And then there’s King Jellyjam himself… an unforgettable, grotesque villain that redefines creepy.
Why It’s a Disturbing Summer Tale
Stine combines a classic summer camp setting with rising psychological tension. The story builds slowly, transforming from playful to panic-inducing. The idea of kids disappearing after losing adds real stakes, and the slow reveal of what lurks beneath the camp is executed brilliantly. It’s weird, it’s wild, and the body horror element is rare for Goosebumps—making it stand out.
A Goosebumps Entry You Won’t Forget
With The Horror at Camp Jellyjam, R.L. Stine shows that the scariest monsters might be hidden behind the smiles of competitive perfection. It’s a cautionary tale about obsession, control, and what happens when you play just to win. Equal parts creepy and clever, this one sticks with you like the smell of something… jelly-like.
