Yes, it's possible, there's two ways to get it. Number one would be a trade, number 2 is completing your Pokedex (Not the national dex, just the pokedex) then go to Littleroot town and go to Prof. Birch's office.
u cant get a tododile in fire red that's in a different game i think in ruby or emerald
u can't... just buy a GAMESHARK, and u can get ANY Pokemon from any version. (even old legendaries, like Suicune from crystal)
You can get it through a trade from someone who has a Chicorita or Bayleef, or you can trade it from Pokemon Heart Gold or Soul Silver, or Migrate it from Pokemon Ruby, Sapphire or Emerald, but it is only obtainable on those last three games if you trade it from the original Gold or Silver.
to get chickorita you have to have Pokemon emerald and get all 202 Pokemon then the professer will give you chikorita cidiquil or todidial then you trade,or you can just use a gameshark or action replay. (other person) I don't think so. You can't get Chikorita in Sapphire and Ruby, except if you use gamesharks.
Pokemon ruby's version IS Pokemon ruby.
Pokemon Ruby has Pokemon that Pokemon Sapphire does not and Pokemon Sapphire has Pokemon that Pokemon Ruby does not.
you can simply all you have to do is compleate the heon pokedex then go 2 pro birch and he'll give you a choice of totadile chicorita or cyndiquil
