Pokédex entries

What each game says about it, in the games' own words.

Red / Blue / LeafGreen	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 / HeartGold	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 slight ly airborne.
Crystal	If one gets close enough to it when it expels poison ous 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.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
