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.
Diamond Pearl Platinum	Lighter-than-air gases in its body keep it aloft. The gases not only smell, they are also explosive.
HeartGold	Its thin, filmy body is filled with gases that cause constant sniffles, coughs and teary eyes.
SoulSilver	The poisonous gases it contains are a little bit lighter than air, keeping it slightly airborne.
Black White	Lighter-than-air gases in its body keep it aloft. The gases not only smell, they are also explosive.
Black 2 White 2	Toxic gas is held within its thin, balloon-shaped body, so it can cause massive explosions.
X	Its thin, balloon-like body is inflated by horribly toxic gases. It reeks when it is nearby.
Y	Lighter-than-air gases in its body keep it aloft. The gases not only smell, they are also explosive.
Omega 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.
Alpha 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.
