Goba appears as a supporting character in the narrative. He is an anthropomorphic groundhog with purple fur and a large, sturdy build. Goba exhibits fanatical devotion to the interstellar Space Show, following its galactic tour with groupie-like persistence. His occupation is farming on planet Wan, where he tends his crops. Goba's barn becomes a crucial shelter and planning base during the climax, aiding the protagonists' mission to rescue their kidnapped companion. At the interstellar festival, Goba actively intervenes against antagonist Neppo's schemes, using his strength to help thwart them. During this intervention, he unexpectedly transforms into a giant, muscular form to breach Neppo's spaceship, an action directly contributing to Amane's successful rescue. Goba's documented presence is limited to this single film appearance.
