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 grandfather Grover Goodway. He is also protective of his grandfather's statue.
Gustavo Goodway 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.
