Don’t worry if you haven’t got a spare Mossy Lure Module in your items list, as there will be an event box in the in-game Shop that features one – and the best news is that it’s completely free to claim!
The following Field Research tasks will be available during the Sustainability Week event:
- Catch 5 Grass-type Pokemon – Turtwig, Snivy, or Chespin encounter

- Catch 3 Trubbish – 1 Silver Pinap Berry
