You had to get a Link at the Nintendo convention, the islands hold deoxy's and ho -oh or somthing.
On Seafoam Islands.
On Cinnabar Islands.
Seafoam Islands
There are 7 non-event islands.
You cannot get all the Pokemon that are in the Pokedex by just using Leafgreen. Instead, you need to trade Pokemon with Firered, Ruby, and Sapphire versions. Also, If you truly want all of them, you need to attend a Nintendo event so you can get a special pass to extra islands in the game.
I don't really know about Pokemon leafgreen, but in Pokemon red you can get it in seafoam islands. Hope this helps!
Trade for them.AnswerTo obtain all of the Pokemon available in Pokemon LeafGreen, you must: - Catch them as you find them throughout Kanto and the islands- Trade with other versions - including FireRed and Emerald- Attend Nintendo events if you want event PokemonOr- Use a cheating device to obtain all Pokemon
