Through Field Research tasks (event dependent)
Occasionally in special event encounters
Using Incense or Lure Modules during events will greatly increase your chances of encountering Grimer consistently.
Can Grimer Be Shiny in Pokémon GO?
Yes, shiny Grimer Pokémon GO is available, including both its standard and Alolan forms.
Events like Sustainability Week are one of the best times to shiny hunt Grimer due to the increased spawn rate. While shiny odds are not guaranteed to be boosted, more encounters mean more chances.

50 Grimer Candy
If you have an Alolan Grimer, it will evolve into Alolan Muk using the same candy requirement.
Using Pinap Berries while catching will help you build candy faster.
Is Grimer Worth Catching in Pokémon GO?
Grimer is worth catching for a few key reasons:
Muk has niche PvP use in certain formats
Useful for Pokédex completion
Good shiny hunting target
