Dig Dug Game Manual

The objective of Dig Dug is to eliminate underground-dwelling monsters by 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).
