Talk to Big Bearmon

Next, travel to the western side of Central Town: Downtown, and speak with Big Bearmon. He’ll tell you that they are about to go underground to get some jewelry and will ask if you’d like to go with them.
Follow the Bearmon Brothers Underground
When you are ready, head to the underground by crawling under the nearby fence. Once inside, head to the side room on the eastern side of the area to find the Bearmon Brothers facing three Geremon. Approach them to trigger an event leading to a battle.

Battle – Geremon x3
For this fight, you will be facing a trio of Level 18 Geremon: Virus Attribute / Mollusk Type / Champion Gen. They are weak to Fire and Electric and resist Earth and Steel. Make sure to bring some Vaccine Digimon that have Fire and/or Electric skills.
Gather Info in the Tavern About the Jewelry
After the fight, you’ll be automatically sent back to the downtown area. Once there, head to the tavern on the northeastern side of the area. Inside, speak with Deputymon standing next to a table and ask about the PlatinumNumemon jewelry.
Get PlatinumNumemon’s Jewelry
After your conversation, you’ll be sent back to the Spiral Waterway. From the entrance, head all the way to the room at the bottom, which you’ll find empty. Next, turn around and return to the entrance to find PlatinumNumemon.

Battle – PlatinumNumemon

Quickly attack this Digimon to prevent it from running away. You’ll engage in a battle with it. PlatinumNumemon is a Level 18 Virus Attribute / Mutant Type / Mega Gen. It is weak to Water and takes no damage from Electric attacks.
Once you defeat the creature, you’ll obtain its jewelry and will automatically be taken back to the Bearmon Brothers. When speaking with them, you’ll have the option to either give it to them for free or trade it for an Aura Skill Disc. Afterwards, the mission will then end.
