Like the above post, the best way is to farm Gold Chests and KI NMs at the same time. Minhocao is harder to find because he roams across a large portion of the map, so you might have someone sub RNG or THF for it.

Using that method, you should net around 3~4 pops/hour sometimes even 6/hour if you already have lights capped+get lucky with the KI's.

That being said, it can be very hard to get lucky with KI's when there are 10 available in chests for that zone.
