Gorrilla is a young male hamster who lives in the home of his owners, a married couple named Kit and Suzie. Physically, he is small with white fur and brown ears, and his most distinguishing feature is the green cap he always wears on his head. His birthday is August 6th.

In terms of personality, Gorrilla is active and playful, often seen engaging in games with the other ham-hams. He possesses a shy and timid side but is also deeply curious. This curiosity manifests in a unique habit: he is constantly looking for new objects to place on his head, with standard pots being a particular favorite he sometimes hides under and drags along with him. While his owners care for him deeply and provide him with a very comfortable and pampered home, including a large cage, Gorrilla sometimes feels overwhelmed by their constant attention and observation.

This feeling of being watched all the time fuels his primary motivation, which is a strong admiration for an independent, free life. He especially admires the wild, owner-free existence of the ham-ham known as Boss or Jefazo. This admiration leads to a significant event where, after Boss rescues him from a dangerous situation during a storm, Gorrilla decides to leave his pampered life behind and become a self-sufficient field hamster, intending to live with Boss forever. During his attempt to live in the wild, he helps store hay and straw, but he eventually learns how difficult life without modern comforts can be. Realizing the hardships of a wild hamster's existence, he ultimately chooses to return home to his owners, who had been missing him greatly.

Throughout the series, Gorrilla plays the role of a friend and playmate within the ham-ham group. His key relationship is with Boss, whom he respects and admires, even wanting to emulate his lifestyle. He also shares a notable friendship with another hamster named Atorín or Atrapadillo, and the two are known to play hide and seek together. In one instance, they become trapped while playing, leading to a rescue by the other ham-hams. Gorrillas development centers on his journey from a dependent, coddled pet to an individual who tests the limits of his own independence. Through his experience trying to live in the wild, he gains a greater appreciation for his home and owners, learning to balance his desire for freedom with the security of his loving family. His notable abilities are not extraordinary but relate to his curious nature and his talent for finding and wearing different objects as hats.
