Grover is the Great-Great-Great-Great Grandfather of Mayor Goodway and Gustavo. He is also the Great-Great-Great-Great-Great Grandfather of Gustavo's children, Julius Goodway and Justina Goodway. Both Mayor Goodway and Gustavo are shown to have great pride and respect for him. As Adventure Bay's first elected mayor, there is a golden statue of him outside City Hall, which both Mayor Goodway and Gustavo are shown to be very protective of.
In "Pups Save a Goodway", Mayor Goodway has his statue sent off to be cleaned in preparation for Grandpa Grover Day and while being transported by Cap'n Turbot back to Adventure Bay it accidentally falls off the boat and into the Bay. The statue is retrieved by Ryder and Zuma, and then is air delivered back to City Hall by Skye. In "Pup a Doodle Do", during her interview with Hello, Adventure Bay!, Mayor Goodway notices his statue's pant leg is dirty and interrupts the interview in order to wipe the dirt off the statue.
Grover Goodway has a mustache and wears a top hat, with a tuxedo. He carries a walking cane.
