you have to migrate
You must get the purified croconaw from Pokemon colosseum or a totadile from Pokemon emerald or one from Pokemon xd gale of darkness then trade it to firered if you have the croconaw you just need to breed it to get totadile.
This is how you spell it: Totadile
level up, it hard with a totadile isn't it?
chicorita,totadile,cindaquil,
Totadile.
After you complete the game, go back to the Prof. and he will have 3 pokeballs. Chickarita, Totadile and Cydaquil. (you can only choose one)
complete the pokedex then talk to profesor elm.
Cyndiqule,Totadile,and Chickorita.
I'd say Mareep, Totadile, Machop, and Growlith.
You have to get it from Professor Elm in the beginning of the game
you need to battle somone what have it!
