You can trade at anytime in sapphire. Except Pokémon from different regions. i.e. Kanto, Johto. After you beat the Pokémon league in sapphire, you just make sure your other fire red leaf green is finally set to trade with Hoenn.
You can't get Totodile in Pokemon Leaf Green Version. Totodile is a Johto Pokemon, while Leaf Green is a Kanto version. The starter water Pokemon in Leaf Green and Fire Red is Squirtle. I don't think you can even get Totodile in a trade.
There are four main regions: Kanto, Johto, Hoenn and Sinnoh. Kanto is in the games Red/Blue, Yellow and Fire Red/Leaf Green. It is also featured in the game only released in Japan called Green. Johto featured in Gold/Silver and Crystal. Hoenn featured in Ruby/Sapphire and Emerald. Sinnoh featured in Diamond/Pearl and the yet-to-be released Platinum. There also other regions. These are Orre, Fiore and Almia. Orre is in Colosseum and XD: Gale of Darkness. Fiore is featured in Ranger. Almia is featured in Ranger: Shadows of Almia.
What game are you referring to? This is what I know: red,green,blue,yellow,Fire Red,Leaf Green:Kanto Crystal,Silver,Gold,heartgold,soulsilver:Johto Sapphire, Emerald and Ruby:Hoenn diamond,pearl,platinum:sinnoh
Johto is inaccessible on Leaf Green although Islands Four to Seven contain Johto Pokemon.
Kanto, the games that have kanto are in the order of new to old: pokemon heartgold & saoulsilver pokemon leaf green & fire red pokemon crystal pokemon gold & silver pokemon yellow: special pickachu version pokemon red & blue
There are Pokémon from Johto in Leaf Green, however you can only find them on the Sevii Islands. (That is after you beat the Elite Four)
No there is not you can only be in kanto or the sevii islands
By trading for them.
