Grimer, the Sludge Pokémon. It was born when sludge in a dirty stream was exposed to X-rays from the moon.
– Dawn’s Pokedex
People thought Garbodor is weird (and don’t get me wrong, it is), but looking back at Gen I, Grimer is basically a sentient pile of sludge/toxic waste, yet people don’t seem to hate it as much. Maybe it’s the derpface?
