Puff Up
The title of this article is conjectural; an official name for the article's subject has not been found, so it has been given a fitting title by the editors. If an official name is found, then the article should be moved to its appropriate title.
Puff Up is Jigglypuff's Final Smash in the video game, Super Smash Bros. Brawl. Once Jigglypuff opens up a Smash Ball, she stands in one spot, and begins increasing in size. She continues growing for about 5 seconds, before she finally reaches the limit, and begins shrinking at a faster rate. Any opposing player that hits Jigglypuff while in this state bounces off of her, in a similar fashion to the Bumper. The distance an opponent flies apparently increases the larger Jigglypuff is, but it only causes damage if any contact is made with Jigglypuff as she is shrinking back to normal size. Jigglypuff is also unable to move around whilst using this move, so one should try and catch an opposing player close to an edge if using this Final Smash. Jigglypuff's size during this Final Smash is incredible - even larger than Giga Bowser himself. This allows Jigglypuff to cover most of the stage area, giving her a high chance of hitting an opposing player. It should be noted that Puff Up is not an actual move within the Pokemon games.
A glitch in the Bridge of Eldin stage can allow the player to permanately play as Giant Jigglypuff after the Final Smash, but the effects wear off if Jigglypuff is knocked out. Furthermore, if Jigglypuff is captured by Yoshi's Egg Lay move during the glitch, she will increase in size exponentially every time she breaks out of the egg.
