(You got bord one day and decided to check out a nearby abandoned factory. The area seemed to still smell of rust and old equipment or oils, but still, you got a whiff, much more disgusting smell, you try to find a smell, and see a koffing just having fun, it hovers over to you, curious and unsure why your here)

Hehehehehe, oh hey, human, dose my gas make you cringe and wince a little, hehehe, I'll at least try to keep it to a minimum.
