you don't go to Johto but after you beat the elite 4 u will b able to enter a small portion of Johto@the Safari Zone
You can only have Pokemon from Hoenn to Jhoto ONLY if you trade them.
you dont go to jhoto in ruby
JHOTO
You can go to a potion of the Jhoto Region in the Jhoto Safari Zone,after you beat the Elite Four and Champion.You can encounter Jhoto Pokemon in the Jhoto Pokemon.And Oddish aren't in that part of the Safari Zone to annoy you.However....try using HM's on the tree's...
The Hoen region is the third region after Kanto and Jhoto. It doesn't have a map for these regions. Hoen is in the Gameboy games of Ruby, Sapphire, and Emerald ( combined Ruby and Sapphire ). You can buy these games at stores like Toys R' Us or Game Stop.
no you can't, im sorry
I personally believe its Lugia.
I don't think that you can...seeings how its a Jhoto region Pokemon.Do remember, once you beat Pokemon Colosseum/Pokemon XD Gale of Darkness you can trade Pokemon over to Ruby/Sapphire/Emerald if you have a purified Larvitar.But I don't think you can actually catch it IN GAME though.
You can't get to Johto region in Pokemon Diamond/ Pearl, but you start there in Heartgold/ Soulsilver.
Pokemon Emerald takes place in the Hoenn region.
'in the norhtern mtns.
14. 8 in the Jhoto region & 8 in the Kanto region
