In "Pups Save a Goodway", he is shown to be a little impatient while waiting for the newly-polished statue of Grover Goodway to arrive.
In "Pups Save Gustavo's Guitar", it is revealed that Gustavo is a talented guitar player. Unfortunately, Mayor Humdinger becomes jealous of Gustavo's musical talent and steals Gustavo's prized guitar for himself. However the Kitten Catastrophe Crew become feed up with Mayor Humdinger's terrible guitar playing and steal it from him to stop him from playing forcing the PAW Patrol and Gustavo to chase after them to recover the guitar, though the KCC hide it inside a log, which ends up putting Gustavo in danger after it rolls down a hill into a ravine, though Gustavo and his guitar are saved by the PAW Patrol.
In "Ultimate Rescue: Pups and the Hidden Golden Bones", a humorous portrait of Gustavo, Chickaletta, and Mayor Goodway can be seen hanging on a wall in the Adventure Bay museum next to the painted portrait of their grandmother Arizona Goodway and her beloved pet Pupaletta.
Gustavo can be a bit impatient at times, as seen in "Pups Save a Goodway". And like Mayor Goodway, he pays great respect for their great-great-great-great grandfather Grover Goodway. He is also protective of his grandfather's statue.
In "Pups Save Gustavo's Guitar", Gustavo is shown to be a talented musician and guitar player, though like with the statue, he worries about his prized guitar when it is stolen by Mayor Humdinger and the KCC. He also shows his impatience once again when he accompanies the PAW Patrol as they attempt to retrieve his stolen guitar. His impatience in retrieving his stolen property also results in him needing to be rescued by the PAW Patrol.
Gustavo has brown skin, with dark brown eyes, hair and a mustache. He wears a white turtleneck and a blue jacket with thin turquoise stripes, blue pants, and a pair of brown shoes.
