Advantages:
Jiggly-puff is has the longest float time in the game and can float even higher (or longer) than Kirby.
she has powerful moves such as rest, when this is used when intercepting another player it causes a lot of damage and the push back is even more powerful, and roll out which also is considerably powerful.
easy to use in maps that require long jumps to platforms.
Disadvantages:
She is very light meaning she can be blown out easy (especially with the fan) .
Moves like roll out can bring you to your own doom.
Rest renders you immobile for a few seconds when used
yes, jigglypuff will be in super smash bros brawl (unfortunately)
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.
You can't unlock Shaymin.
if you mean playing her then yes,she is a playable character
you get jiggly puff by completing all game events
It depends on you usually it will be jigglypuff.
Which game? If you are on about super smash bros brawl, then the awnser is they are both in it :)
Pikachu, Jigglypuff, Lucario, and Pokemon Trainer (Charizard Ivysuar and Squirtle)
Go to Bridge of Eldin and wait for the bridge to go out. When the portal show up, jump in the gap while as jigglypuff with a smash ball and activate it. See the rest for yourself.
