Shenron

Dragon Balls
The dragon balls are scattered throughout the different maps and change locations every 30 minutes. As you gather them, they will appear in the main menu showing which ones you have and which ones you are missing, once you gather all seven, a "Summon Shenron" button will appear in the main menu. If you press the button the sky in the background will turn dark and shenron will appear to grant you one of four wishes.
