You can't unlock Shaymin.
It depends on you usually it will be jigglypuff.
yes, jigglypuff will be in super smash bros brawl (unfortunately)
Beat the Subspace Emissary, go back to that mode, Go to the Swamp level and in the middle of the level, there is a door that was not there before. Enter and you fight Jigglypuff, beat it to unlock it.
It will come up randomly as will Toon Link and Wolf. I got Jigglypuff from completeing most of the characters on classic mode.
On large levels, Jigglypuff.
use jigglypuff :(
Yes but unlike the first two smash bros jigglypuff is one of the last ones to get.
There are a couple of ways: Do 350 matches of brawls, then fight Jigglypuff and win in a brawl Complete the Subspace Emissary, then complete Classic with any character (someone told me except Ike) Complete Subspace Emissary, then events #1-#20, then fight and beat Jigglypuff in a brawl Complete Subspace Emissary, then go on the stage "The Swamp" again. There will be a door (quiite late on) in there which leads to a brawl with Jigglypuff in Pokemon Stadium 2. Win, and you unlock Jigglypuff, and also add her to your Subspace Emissary Team.
you get jiggly puff by completing all game events
if you mean playing her then yes,she is a playable character
The easiest way: have him join you in Brawl.
i think so
