The objective of Dig Dug is to eliminate underground-dwelling monsters
The objective of Dig Dug is to eliminate underground-dwelling monsters by either inflating them with an air pump until they explode, or by dropping rocks on them. There are two kinds of enemies in the game: 'Pookas' (a race of round red monsters, said to be modeled after tomatoes, that wear yellow goggles), and 'Fygars' (a race of green dragons that can breathe fire while their wings flash).
