Pokédex entries

|---|---|
| Yellow | It lives and grows by absorbing dust, germs and poison gases that are contained in toxic waste and garbage. |
| Stadium | A twinned KOFFING that forms on rare occasions where poisonous gasses pool. Its two toxic gasses appear to be different. |
| GoldStadium 2 | If one of the twin KOFFING inflates, the other one deflates. It constantly mixes its poisonous gases. |
| Silver | 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. |
