Instructions
Hook the D-3 Digivice to your belt or pants and walk. The D-3 Digivice is powered by a pedometer so you have to move in order to walk around the Digital World. You can also shake the D-3 Digivice to make it progress.
Press the large white button in the middle of the D-3 Digivice when it beeps to see what you've found. If you found a digiegg, which occur randomly throughout the world, pick it up with the same button. More digieggs appear in level 2 and higher of the game.
Defeat Baihumon at the end of the game to get the final digiegg. Clear level 3 twice and have over 120,000 steps. Make sure every available Digimon is in your party, and that they can digivolve into their ultimate forms. Defeat Azulongmon three times and shake the D-3 Digivice until it beeps. Click on the white button.
Digivolve all your Digimon into their ultimate forms by clicking on them with the "Up" and "Down" buttons and selecting "Ultimate" from the list. Click on the white button to finalize it. Shake the D-3 Digivice to power up your attack. You'll get the miracle digiegg for beating this boss.
