Hurley is a white-brown male guinea pig with white fur on his face, hands and body. His appearance is kind of cute, but he is greedy with food. He joined G-Force when he met Darwin, Juarez and Blaster at the pet shop. His not-so-enemy is Bucky the hamster. Hurley notices a birthmark on Darwin's rump that looks identical to his own and believes that Darwin is his brother, even though he repeatedly denies this to Hurley. He follows Darwin around while overcoming obstacles, such as dogs and the FBI, and helps defeat "Mr. Yanshu," who turns out to be Darwin's former secret agent Speckles. Hurley's nickname is Rookie, according to the badge that Darwin gives him at the end of the movie from Ben.
