For this you need the livingtoy "WALKBOMB". When the WALKBOMB walks it charges up. So walk into a town or somewhere where you won't be attacked. Tape the foward button or analog joy stick up and aim the WALKBOMB so that he walks but stays facing a wall and doesn't move sideways. These are the results: In 10 minutes: you get 2000 in distance, which is about 100 damage. In about an hour you get 6,000 damage
