Go into Pokemon mansion which is found on cinnibar island once inside wait until a wild Pokemon appears. Grimer is not that rare to find but you can find it.
You find Grimer in the Fiery Path. They are rare is it may seem that they are not there but they are. Its worth the time getting Grimer then evolving it to Muk, because Muk is probably one of the stronger Poison type Pokemon that are in Emerald!
its rare in fire red but here is the location of this pokemon: Pokémon Mansion, Celadon City
keep catching grimer when you are done an old man gives you a 10 rare candies!!!!!!!!!!!!!!!
Yes, Grimer can be caught in Pokemon Fire Red.
Grimer does not have a pre-evolution. The Pokemon before Grimer in the PokeDex is Dewgong, evolution of Seel.
Which game? Grimer > lvl 38 > Muk In Firered and Leafgreen you can find them in Celadon City by fishing, but that is pretty rare, and the Pokemon Mansion eveywhere.
grimer is in route 212
For Grimer to evolve, get him to level 38.
Safari zone, but I can't remember which area. Probably swamp. Hope I helped!
Yes you can. It is only available in the Firey Path. But they are rare (Only a 2% chance you will run into one.)
You can nothing to kill all Grimer and some rare Muk.
