This page offers a guide on how to complete Request 43: More New Wares in Pokémon Legends: ARCEUS (PLA).
Before you can access this request, you’ll need to have completed Request 23: Getting Ahold of New Wares (Choy’s first request). You’ll then be able to pick this request up from Choy, who will ask you to deliver x3 Pop Pods to Tao Hua.
Where to Find Pop Pods
Pop Pods can be found in abundance right on the coastline in Cobalt Coastlands. They’re red balls on short stalks. You should be able to get enough in one trip, then head back to Jubilife Village and down to the basement of Galaxy Hall. Hand over the Pop Pods to Tao Hua. Then, report back to Choy to finish up the request and unlock some more wares at his shop!
