The rookie security guard is a minor character that appears in the episode "Something You Can Do with Your Finger".
During his first day on the job as a security guard of South Park Mall, the rookie takes advice from the veteran security guard, approaching shoppers sternly, including a supposed "terrorist", before asking them to move along.
Both guards later approached the Fingerbang crew, accusing them for starting an orange smoothie riot over a Nissan Sentra. As the Fingerbang crew makes their escape, the veteran guard ordered the rookie to give chase, but the latter could only stare.
The rookie was finally seen with the veteran guard during Fingerbang's performance in the mall.
He has brown hair and wears the mall's security uniform, which consists of a buttoned blue shirt, black belt and blue jeans.
