ディグダグ
"Dig Dug" is a maze video game. Controlling the titular character, the player's objective is to eliminate the enemies on each screen; these being Pookas, red tomato-like creatures with comically large goggles, and Fygars, green dragons that can breathe fire. Dig Dug can defeat these enemies by using a bike pump to inflate them with air until they explode, or by crushing them under large falling rocks. Bonus points are awarded for squashing multiple enemies with a single rock, and dropping two rocks in a stage will cause a bonus item to appear in the middle of the screen, which can be eaten for points. Once all the enemies have been defeated, Dig Dug progresses to the next stage.
