It is one of the three starter pokemon you choose from at the very beginning of the game. if you didn't choose it, there is no other way to get it unless you ask for it on the GTS
with poke balls
If you mean starters you can get Totodile, Chickorita, or Cyndaquil!
todidile,cyndiquil,chickorita just the old Pokemon for the old silver and gold games
you get chickorita has a starter Pokemon in soul silver if i was you i would pick a tododile why should he/she want to see a chickorita if he did choose it? he/she probaly choosed cyndaquil and want a chickorita to his/her pokedex or to catch it, so that is not a good answer..
Chikorita evolves into Bayleef at level 16.
You can't find Chickorita in Pokemon platinum. You have to trade with someone who has that Pokemon Or you can migrate from emerald or wait until heart gold and soul silver comes out
-Cyndaquil (evolves into Quilava evolves into Typhlosion) - Todadille (evolves into Crocnaw evolves into Feraligatr) - Chickorita(evolves into Bayleaf evolves into Meganium)
Those Pokemon are starter Pokemon in silver and gold, but those are color games.
sorry you have to trade it to Pokemon soul silver
Soul silver is AWESOMENESS!! yes GET IT
According to Serebii.net there are 493 Pokemon in Soul Silver.
You can't do Pokemon contests in Pokemon soul silver.
