Disaster Will Strike 7 continues the extermination of the evil eggs. Use natural disasters to kill them as fast as possible, applying strategies. These eggs that don't hatch out can't breed anymore, or else the planet is doomed. Stop the population from growing, using wind, earth, water and whatever else nature provides to strike them out. The Mouse is the only control needed once a good plan is set in mind. Make sure to destroy them quickly, not because they can breed but to avoid losing too much points. The faster the level is cleared, the better for the final score.
