Instructions
Begin a new game of "Pokemon: SoulSilver." Follow the onscreen prompts to create your customized character and begin his quest in Pokemon training.
Travel to the Moo Moo farm located west of Ecruteak City. There, you will find a character who rasies Miltanks. Enter the westernmost entrance to find the owner of the farm. Press the "A" button to speak with her and she will tell you about her current problem.
Heal her injured Miltank by giving it 10 oran berry items. Once you give the Miltank the items, it will recover from the injuries. Speak to the girl on the left hand side of the barn and she will give you the ball capsule case.
