Buddy finds Wendy and Elliot stranded in their crashed trailer, so he suggests that they stay at Camp Jellyjam until the counselors find their parents. Wendy notices something suspicious about Buddy and the other counselors: they always want her to participate in a sport and be the best, like her life depends on it. She then discovers that Buddy and the other counselors are the brainwashed slaves of King Jellyjam.
Buddy has blonde hair and blue eyes. He is described by Wendy as having "about two thousand teeth." This describes his seemingly-permanent, huge smile.
He is dressed in the Camp Jellyjam's uniform: a white t-shirt tucked into baggy white shorts. Buddy wears a pin on his shirt that says, "ONLY THE BEST" in bold black letters.
In an interview, illustrator Tim Jacobus shared the design requests that Scholastic had sent him for The Horror at Camp Jellyjam prior to the book's release; the message mentions that Buddy is about 17 to 18 years old.
Buddy, when introduced, is a friendly person and a helpful guide. However, when Wendy tries to lead the enslaved children out of King Jellyjam's cave, Buddy becomes aggressive. He sprints toward the children but is stopped dead in his tracks by a police officer. Buddy suddenly snaps out of his hypnosis. He is unsure of his own identity, and he doesn't know where he is. Buddy later apologizes to the children for his earlier actions. Buddy is also very resiliant physically (at least while under hypnosis), at one point taking a full force blow to the ribs by a baseball bat by Wendy and feeling no pain.
