Al you gotta do is recruit one of them just keep fighting them till recruit one
keep on battling them and buy all friend areas
You can in Mystery Dungeon Blue and Red. You can get Articuno in Time and Darkness too, if you use wonder mail. From N.S.
u make the legendary birds in ur teamand u will know that alakazam is at the way to the wiscrash pond talk it tells u to go to the legendary island friend area and u will get there.
You will gain access to the Silver Trench which contains Lugia on the 99th floor if you have recruited all three legendary birds and talk to Alakazam and then go to the Legendary Island friend area.
Access mystery dungeon and go to wondermail generator and then do a mission and hopefully you have it. But if that does not work, then go to "legendary isle" friend area and then you'll get it. P.s: Try the 'friend area' first...
If you are talking about Pokemon mystery dungeon red rescue team or Pokemon mystery dungeon blue rescue team then: Talk to alakazam, he'll mention something about the 3 great birds. once you go to them they will give you a stone which allows you into a new dungeon which has lugia.
After you beat the game, go back to the places you originally battled them. You don't have to buy their friend area (it comes with them). If you only have one Pokemon on your team, it is very likely that the legendary will want to come on your team!
I think you are supposed to go to a dungeon where you find Lugia. It has many floors. At least that's what I heard on You-Tube...
Get one of the legendary birds to join your team.
I dont know what 3 youre talking about but for the 3 birds Just keep going back to their homes and rebattle them and for the 3 dogs you just do the same.
You talk to Alakasam then when you have recruited the legendary birds(zapdos e.t.c) sometime when you talk to them they will give you a feather or something(can't remember what type LOL)then go to SILVER TRENCH () () (-_-)
You just have to keep fighting them, eventually one will ask to join, then the chances of getting the other 2 are increased because you have the island.
