You need to do the Poke Transfer after you beated N at N's Castle, (the leader of Team Plasma.) Then the Marvelous Bridge will be open. Then you go through it then you will appear in Route 16 then in the middle of Route 16, you find a lab.
That is the Poke Transfer Lab.
You can only get it by transfering from another game.
No, you cannot get mew in Pokemon white or black
You can't exactly 'find' Mew in Pokemon Black or White. The only way to obtain Mew in the game without cheating is to transfer it from an older Pokemon game, trade with someone on the GTS (which may be hard since everyone asks for impossible to get Pokemon), or somehow find it in the Dream World. :)
Unfortunately, you can't find Mew anywhere on Pokemon White. You can, however, migrate it from Pearl, Diamond, Platinum, Heartgold or Soulsilver. As far as I know of, that's the only way to get a Mew on the game (Unless you use an Action Replay and hack the Pokemon Modifier Code)
you can find a mew mew power costume on ebay.
You cant catch mew.
you can find mew ichigo/zoey mew lettuce/bridget mew pudding/kiki mew zachruo/renee and mew mint/corina on ebay!
well um my nephew said the 1st one is on route 6 hope it helps
Mew is unobtainable in Pokemon Black or White. To get it, you must either trade or wait for an event giving away Mew (or hack or cheat!)
its impossible unless a mewtwo event happens...
You'll need to trade for it or transfer it from the older DS Pokemon games.
You have to migrate mew from generation 3 as of now.
