Appears in filthy areas. Thrives by sucking up polluted sludge that is pumped out of factories.
Yellow Made of hardened sludge. It smells too putrid to touch. Even weeds won't grow in its path.
Gold As it moves, it loses bits of its body from which new GRIMER emerge. This worsens the stench around it.
Silver Wherever GRIMER has passed, so many germs are left behind that no plants will ever grow again.
Crystal When two of these POKéMON's bodies are combined together, new poisons are created.
Ruby GRIMER’s sludgy and rubbery body can be forced through any opening, however small it may be. This POKéMON enters sewer pipes to drink filthy wastewater.
Sapphire GRIMER emerged from the sludge that settled on a polluted seabed. This POKéMON loves anything filthy. It constantly leaks a horribly germ-infested fluid from all over its body.
FireRed Sludge exposed to X rays from the moon transformed into GRIMER. It loves feeding on filthy things.
LeafGreen Appears in filthy areas. It thrives by sucking up polluted sludge that is pumped out of factories.
Emerald Born from polluted sludge in the sea, GRIMER’s favorite food is anything filthy. They feed on wastewater pumped out from factories.
