but before they can do any harm, Magnemite and Magneton appear out of nowhere and shock the sludge Pokémon into submission. In the Pokémon animé, it appears with evolved form Muk in a deserted power plant where it encounters Ash Ketchum and friends. If hit with three Pester Balls, they will evolve into Muk. Grimer are also found in the Nintendo 64 game Pokémon Snap in the Cave Course (which is not quite as dirty an area as the other locations where it is found in the other Pokémon games). For battle, trainers are best served by Grimer's evolved form Muk, but must be patient whilst training Grimer-it evolves into Muk at a relatively high Level 38. However, its other stats, particularly Speed and Special Attack, are very poor. Grimer is comparatively stronger than many other Basic Pokémon that evolve, in terms of Hit Points and Attack stats. It can also be snagged in Pokémon XD: Gale of Darkness. It can also be caught in Ruby, although it is much rarer in this version. In Pokémon Yellow only, it can be found in the abandoned power plant.Grimer can also be found in Sapphire or Emerald in the Fiery Path near Lavaridge Town. In Pokémon Red, Blue, Yellow, FireRed and LeafGreen it can be found in the abandoned Pokémon Mansion of Cinnabar Island and the polluted pond in Celadon City. Grimer is found in dirty, run-down or polluted areas in the video games. Grimer also tend to fuse together, creating new poisons. New Grimer are also formed from bits of sludge that Grimer leaves in its trails. If Grimer gets attacked and gets split in half, it will either put itself back together or duplicate into more Grimers, meaning that it reproduces asexually. Another theory is a lab accident in a factory. It is believed to have originated from a polluted seabed. It is unlikely that Grimer has any internal organs, as it was brought to life from sludge. If you stick your hand in Grimer, it will be very hard to get it out. It enters sewers and other areas with great ease due to its rubbery and semi-viscous body for example, it can enter barred-off areas by slipping between the narrow bars. It survives and matures by sucking up polluted sludge that is pumped out of factories, adding toxic waste to its already toxic girth.

Grimer thrives in filthy areas, such as factories, garbage dumps, sewers and polluted water systems. It likes hanging around Team Rocket for some reason. It smells incredibly foul, and can influence the abandonment of entire cities due to its polluting nature-even weeds don't grow where a Grimer has appeared. Grimer is composed primarily of putrid, hardened sludge and grime.
