Rover is the tritagonist of the computer game "Putt-Putt Goes to the Moon" and a minor character in "Putt-Putt Enters the Race" and "Putt-Putt: Pep's Birthday Surprise". He is a space car and a new friend of Putt-Putt's. It is unknown who did Rover's voice in the game, as his voice actor was additional.
Astronauts brought Rover to the moon from Earth and abandoned him when they returned.
Rover only makes one little brief appearance in his debut game.
Later, when on the first crossing of a bridge over moon goo, Putt-Putt falls into the moon goo, he honks the horn for help, and Rover helps him out, and then fixes the bridge so that next time Putt-Putt crosses (if ever), it doesn't collapse again. He shows Putt-Putt a space rocket that is owned by two conjoined aliens (with the male on the female's left), and is missing some parts.
Rover is the one who helps Putt-Putt (and Pep) up so they can get the steering wheel for the rocket off a high cliff that Rover's (whatever that part is) can't reach.
After all of the parts are gathered and Putt-Putt reassembles the ship, he takes the three of them back to Earth.
Rover reappears in "Putt-Putt Enters the Race" as a worker at an ice cream drive-in where milkshakes and cartons of milk are sold, but he gives them to him for free as thanks for his assistance.
Again, Rover reappears in "Putt-Putt and Pep's Birthday Surprise" as an employee of an ice-cream stall and, again, gives it to him for free.
