Top-grade perfume is made using its internal poison gases by diluting them to the highest level.
Crystal When it inhales poisonous gases from garbage, its body expands, and its insides smell much worse.
Ruby WEEZING loves the gases given off by rotted kitchen garbage. This POKéMON will find a dirty, unkempt house and make it its home. At night, when the people in the house are asleep, it will go through the trash.
Sapphire WEEZING alternately shrinks and inflates its twin bodies to mix together toxic gases inside. The more the gases are mixed, the more powerful the toxins become. The POKéMON also becomes more putrid.
Emerald By diluting its toxic gases with a special process, the highest grade of perfume can be extracted. To WEEZING, gases emanating from garbage are the ultimate feast.
FireRed Very rarely, a sudden mutation can result in two small KOFFING twins becoming conjoined as a WEEZING.
