'''Puff Up''' ({{ja|おおきくなる|Ōkikunaru}}, ''Grand Growth'') is [[Jigglypuff]]'s [[Final Smash]].

When used, Jigglypuff slowly inflates itself to a very large size, enough to almost entirely cover a small stage. While growing, fighters and items will be pushed away. Once Jigglypuff reaches its full size, it shouts "JIGGLY!!!" and returns into it's normal size.

In ''[[Super Smash Bros. Brawl]]'', when Jigglypuff shouts, it causes a massive [[push]] that will most likely [[KO]] any enemies too close to its body, especially if they have used up their [[jump]]s trying to avoid it, or prevent them from recovering. While Jigglypuff is deflating, it will cause 17% damage and powerful semi-spiking [[knockback]] upon contact, similar in power to the push effect. This is in effect until Jigglypuff is back to its original size, making contact dangerous until the Final Smash ends.

Puff Up received some changes in ''[[Super Smash Bros. 4]]''. Instead of producing a large windbox when Jigglypuff shouts, the move instead hits one time for 17% damage, and has no hitbox as it shrinks. This lowers the move's potential damage output, and makes it worse at gimping recoveries, but makes it easier to deal some damage to the opponent, and makes the move more effective at higher percents, as the former windbox used set knockback.

Puff Up was changed again in ''[[Super Smash Bros. Ultimate]]''. Jigglypuff now looks angry instead of it default appearance of a smile and fully-opened eyes. Just like other Final Smashes in ''Ultimate'', this one is faster, both in inflating and deflating. Once fully inflated, Jigglypuff will shout as usual, and then quickly and briefly expand further and "pop" before rapidly deflating. It now deals 10% damage with set knockback when Jigglypuff shouts and then an additional 25% with the "pop" instead of a 17% from the prior games. It is also no longer a semi-spike, but does more knockback overall. This makes the move much less suited for gimping, but harder to avoid getting hit by, especially when used under the stage, and more offensive-oriented.

While the move covers a very large range, it loses potency quickly on larger stages, and cannot affect anything below Jigglypuff (though this can be remedied by having Jigglypuff start the attack from below the stage, which will let it expand up and ''through'' the stage). It also pushes teammates regardless of if [[Team Attack]] is on or off. Additionally, the move can be avoided on smaller stages by fighters with good recoveries, or by exploiting ledge invincibility, however some fighters may struggle to avoid the move, and in free-for-alls it's very likely that at least one opponent will be hit by the move.

*In ''Smash 4'', most of Jigglypuff's attacks cause it to look in a certain direction while performing the move, and if this applies to the move Jigglypuff broke the [[Smash Ball]] with, then after using the Final Smash, it will look in that direction until it uses an attack or air dodge. This glitch can even carry over into two of its victory animations (with the third cancelling the glitch due to its eyes already being scripted to look to its right). This glitch was fixed in ''Ultimate''.
