yes you can
There is a building in Celadon city called Celadon Condominiums enter it and go into the elevator and go to 3rd floor. there is a man looking at a spinning globe and he gives it to you.
To catch a Metapod in Pokemon SoulSilver (And in Pokemon HeartGold as well), you have to enter the Bug Catching Contest at The National Park on Tuesdays, after you obtain the National Pokedex.
There are some Pokemon you can transfer from Battle Revolution but when transferring from Diamond/Pearl/Platinum, it only copies them and it copies everyone you have within your game and the Pokemon that you transfer are a surfing Pikachu, an Electivire and a Magmortar. In order to get Pikachu with the move Surf is you have to beat the game and with Electivre and Magmortar, you have to enter a code into your Self Introduction and you also get a gold and sliver if you enter both of the right codes in your Self Introduction.
after you get surf, surf down from olivine city and you will find them, but you will need whirlpool to enter, and you have to defeat a specific gym leader i think it is the 7th one in mahogany town
After you've defeated Red (meaning you've also collected all 16 badges and beaten the revamped Elite Four) Professor Oak will give you a choice of one of three of the Kanto starters. Now go see Mr. Pokemon in Johto. He will give you the Red Orb. Take it to Route 47 and enter the Embedded Tower. For SoulSilver, you can catch Groudon here. Kyogre can only be obtained via this method but in HeartGold. Then, transfer both Pokemon to one game and bring them to Professor Oak. He will give you the Jade Orb, and return with it to the Embedded Tower to catch Rayquaza. You need to have a Groudon caught in SoulSilver and a Kyogre from HeartGold (that is, not transferred from Emerald, Ruby, Sapphire, etc).
You can't.
Some legendary Pokemon can't enter.
Underground in Goldenrod City.
No!
You must have beaten the Elite Four and Champion.
You need a Rotom to go up the elevator.
The non cool thing about the battle frontier is you can't enter legendary Pokemon however you can go around that rule by having the following Pokemon: Regice, Registeel, Regirock, Articuno, Zapdos, Moltres, Raikou, Suicune, Entei, Latios, Latias. For some reason those are the only exceptions to the rule of legendary Pokemon maybe because the rest of the legendaries are overly powerful.
Sorry, but you cant enter kanto from Pokemon platinum. Unfortunately, that is only possible in Heartgold and Soulsilver. Hope this helps.
There are 3 ... you can get the Legendary Bird Pokemon ( HO-OH ) you can find it at the ten tower ... you must have a rainbow wing to enter the tower. but the other 2 Legendary Pokemon i don't think you can get them.
you have to enter this code and the it will give you a box then click okay!enter this: QTU4-THE6-UEN5-UWBG5that should do it!
u need to go to the cave and enter the waterfall and then you will battle lugia (also know as the sercet room)
Once you leave your house, go to the house on the left. This is Professor Elms Lab. When you enter, talk to the man in the white coat at the back. There will then be a cutscene and you can choose your pokemon out of:CyndaquilTotadileChickorita
