Lore
Ruby
From MUK’s body seeps a foul fluid that gives off a nose-bendingly horrible stench. Just one drop of this Pokémon’s body fluid can turn a pool stagnant and rancid.
Sapphire
This Pokémon’s favorite food is anything that is repugnantly filthy. In dirty towns where people think nothing of throwing away litter on the streets, MUK are certain to gather.
