The Security Corps will need help dealing with the Bidoof that are bothering the village.
The Request
Check on the chalkboard in Galaxy Hall to accept this request.
Talk to Tsumugi
Tsumugi is near the Front Gate of Jubilife Village. Talk to her to proceed.
Add a Bidoof to Your Team
If you need a Bidoof, you can catch one in Obsidian Fieldlands, in the Aspiration Hill, Horseshoe Plains, and Tidewater Dam areas. Add one to your team (if it isn't already on your team) by visiting the Pasture in Jubilife Village or by talking to the Galaxy Member in a base camp.
Find the Three Bidoof
One Bidoof is just outside of your quarters. Approach it and there will be a cutscene.
One Bidoof is east of the southern gate of the village, looking into the Pasture. Approach it and there will be a cutscene.
One Bidoof is behind the southwest buildings in the village, next to a cart. Approach it and there will be a cutscene.
Reward
After you find all three Bidoof, you get 1 Rare Candy.
