What are the NPC fetch quests in Pokemon Sun / Moon?
Solution 1:
I haven't beaten the game yet, but here's the list of ones I have encountered so far.
Melemele Island:
- Route 2 Pokemon Center - girl with hat - Cutiefly
- Route 3 - male sightseer - Rockruff
- Hau’oli City Tourist Bureau - scientist - register 10 Pokemon species in your Pokedex
- Hau’oli City Pokemon Center - blonde woman - Drifloon
Akala Island:
- Heahea City clothing store - man - Pyukumuku
- Route 5 Pokemon Center - scientist - Feebas
- Route 8 Aether Foundation trailer - Aether employee - Stufful
- Konikoni City Pokemon Center - Aether employee - Oranguru/Passimian
Ula’ula Island:
- Malie City clothing store - collector - Togedemaru
- Malie City Library - Samson Oak - Alolan Persian (must have the Persian in your party for this quest)
- Route 16 Pokemon Center - Aether employee - Mimikyu
Poni Island:
- Seafolk Village - woman in Steelix boat - Alolan Raichu
Solution 2:
There is missing one in Akala Island in which you could do many times: you need to make 6 Pyukumuku leave Hano beach. You do not battle them, tho.
