Pokédex entries

Red
Blue
Because it stores several kinds of toxic gases in its body, it is prone to exploding without warning.
Yellow In hot places, its internal gases could expand and explode without any warning. Be very careful!
Gold Its thin, filmy body is filled with gases that cause constant sniffles, coughs and teary eyes.
Silver The poisonous gases it contains are a little bit lighter than air, keeping it slightly airborne.
Crystal If one gets close enough to it when it expels poisonous gas, the gas swirling inside it can be seen.
Ruby If KOFFING becomes agitated, it raises the toxicity of its internal gases and jets them out from all over its body. This POKéMON may also overinflate its round body, then explode.
Sapphire 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.
FireRed Its thin, balloon-like body is inflated by horribly toxic gases. It reeks when it is nearby.
LeafGreen Because it stores several kinds of toxic gases in its body, it is prone to exploding without warning.
Emerald Getting up close to a KOFFING will give you a chance to observe, through its thin skin, the toxic gases swirling inside. It blows up at the slightest stimulation.
