Cons
- Light, dies quickly. To prevent this try to use the hit and run tactic.
- Slow, slowest character in the game. This is no big deal as you should probably be in the air most of the time anyway
- Up B and Down B leave it free to attack. You should rarely use Up B and if you use Down B and it connects they will get launched in the air or possibly die meaning you won't get hit. Probably shouldn't use this in group matches.
- B is easy to self destruct with. Although you can control where you go, so don't fall off the edge.
- Attacks aren't the strongest. So use a lot of combos and juggle your opponent a lot. Use mainly aerial Forward A and Backward A
- No projectiles. This is tough to deal with.
Pros
- Great recovery.
- Good aerial attacks.
To Defeat
Be Ike, Marth, Ganondorf, or anyone with strong close ranged A attacks. Because Jigglypuff has no projectiles it must get close to you. From here just attack with your strong A attacks.
Final Smash
Jigglypuff grows really big. When he shouts out "Jigglypuff!" anyone touching him will fly off the screen. This is great on small stages (Battlefield, Final Destination, Wario Ware, etc.), but horrible on large stages (Hyrule Temple, etc.). To use on small stages, just go to the bottom platform. Get to the middle and press B. To use on large stages, throw someone off the edge, go close to the edge and press B. Hopefully they will either not be able to get back on or touch you while you scream.
To avoid the Final Smash
On small stages: Grab the ledge, don't get back up until half a second after she starts to shrink. If you have a character that can jump multiple times or floats (Peach, Kirby, Metaknight, Jigglypuff, Etc.) Jump off the stage as late as possible, but before the scream. Don't die but get pretty far from Jigglypuff. As soon as he starts to shrink hop/glide/float/fall/etc. back on.
