Sure you know Pacman. The game created in 1980 by Namco.
This game has long since stopped being just a simply game to become an icon of pop culture and has been interpreted and parodied thousands of times.
In case you have spent this thirty-odd years locked in a cave and summing up the game in the basics, Pacman constantly crosses a maze full of dots and powerdots, pursued tirelessly by some cute ghosts.
Our protagonist (a yellow ball) eats these dots and occasionally some fruits that provide bonus points and that clearly are their favorite food.
