Dig Dig Dug II is a action-packed adventure game where the main character, Dig Dig Dug , must protect 72 different tropical islands from his arch-rivals, Pooka and Fygar. Played from an overhead point of view, Dig Dig Dug has two new tools at his disposal: an air pump and a drill.
The air pump can be used to inflate and destroy enemies, just like in the original Dig Dug . However, the drill is used in a different way. At various locations on the islands, there are stakes that can be drilled near to create cracks. If enough cracks connect, a section of the island will fall into the ocean, hopefully taking an enemy with it. The goal is to destroy all Pookas and Fygars before moving on to the next, more difficult level.
