Choy needs more items for his shop again. Time to help him with the negotiations again. After all, you also need more items. Tao Hua is back to being unreasonable, but this time Hearty Grains won't do the trick. Here's how you complete the request. Newest items in Pokémon Legends: Arceus.
You will unlock this request after completing the task of calming Ursaluna and unlocking the Cobalt Coastlands. You must also have completed Choy's previous request, Get New Items. Once done, talk to Choy and he will tell you that Tao Hua will no longer sell him goods. You need some Pop Pods to make it more reasonable.
Head to Beachside Camp or Coastlands Camp in the Cobalt Coastlands. Head down to the beach and look for the Pop Pods along the coast. This object looks like a red ball on the beach. Collect three, but watch out for the different Pokémon that may attack you in the process.
Once you have three Pop Pods, head back to Jubilife Village and talk to Tao Hua in the basement of the Galaxy Team HQ. He will agree to give new merchandise to the general store owner. He talks to Choy and gives him the good news. As a reward, you will have additional items that you can purchase from the shop.
