Sustainability Week Collection Challenge Pokémon list in Pokémon Go

The Sustainability Week Collection Challenge will be available in Pokémon Go until Monday, 25th April. By completing this challenge, you’ll earn a selection of rewards and add progress to your Elite Collectors medal.

It’s important to note that two of the Pokémon listed below can only be found by using a Mossy Lure on a PokéStop during Sustainability Week 2022. Thankfully, there is a free Mossy Lure bundle available in the in-game shop during this event, so you don’t need to worry about purchasing one.


Here are the Pokémon in the Sustainability Week 2022 Collection Challenge, along with how to find them:

  • Cherubi - In the wild, attracted to Mossy Lure and field research task (Catch 5 Grass-type Pokémon)
  • Grimer - In the wild
  • Gloom - Attracted to Mossy Lure
  • Weepinbell - Attracted to Mossy Lure
  • Trubbish - In the wild and field research task (Catch 3 Grimer)
  • Grotle - In the wild and attracted to Mossy Lure

For completing this Collection Challenge, you’ll receive 10,000 XP, 15 Great Balls and a Meganium encounter.

Currently available is the Astral Eclipse event, which brings the A Cosmic Companion special research quest of the Season of Light to a close. You can also finally evolve Cosmoem into Solgaleo or Lunala! Elsewhere, be sure to use Daily Adventure Incense for the chance of encountering Galarian Articuno, Galarian Zapdos and Galarian Moltres.

You can collect event exclusive field research tasks for Sustainability Week 2022 by spinning PokéStops in Pokémon Go.

  • Catch 3 Grimer reward - Trubbish encounter
  • Catch 3 Trubbish reward - 1 Silver Pinap
  • Catch 5 Grass-type Pokémon reward - Turtwig, Snivy or Chespin encounter
  • Walk 1km reward - Cherubi encounter
  • Walk 3km reward - Phantump encounter
