Walkthrough ( Video )
1. Find your trainer in the Job Center to receive the Training Badge.
2. Master Mo Mo gives you a Fervent Pill and asks you to seed the Bull Monsters in Mystic Castle.
3. Right click the pill, which lasts 1 minute and causes you to lose 10 percent of your current HP every 10 seconds.
You can probably get a Burnt Bull Horn in your inventory when you kill some of the Bull Monster during the effects of the pill.
Bring Master Mo Mo 10 horns.
3. Take the Ghost Mirror and head to the Mystic Castle. Use it according to the instructions you were given. Set the traps at the shining spots, then herd the Mad Bulls into them and kill them. The Ghost Mirror will then absorb its ghost and turn it into a ghost crystal. Just take 3 Bull Ghosts back to Mo Mo.

4. Kill the Bull Master in the Mystic Castle(186, 359) and give the Bull Heart to Mo Mo. He will award you with an Ultra Badge. Swap it for a reward from your trainer (the one who can promote you) in the Job Center.
