Koffing embodies toxic substances. It mixes the toxins with raw garbage to set off a chemical reaction that results in a terribly powerful poison gas. The higher the temperature, the more gas is concocted by this Pokémon. Lighter-than-air gases in its body keep it aloft. The gases not only smell, they are also explosive. Its thin, balloon-like body is inflated by horribly toxic gases. It reeks when it is nearby.
