Hint: Digi-Egg:
After you get to the little guys who give you the Digi-Eggs, when you are at the map you will see another place's steps. Exit the town where the little guys were. It will be available again. Go into it and they will give you D-Power and another Digi-Egg. You can get all but two of the Digi-Eggs this way.
