Puff Up

Puff Up is Jigglypuff's Final Smash in both Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U. When activated, Jigglypuff will begin to inflate itself to a very large size, encompassing a large portion of the stage. Opponents that make contact with Jigglypuff will be pushed to the side. Once Jigglypuff reaches its peak height, opponents around it will be slightly damaged and launched to the side. Jigglypuff will then rapidly shrink to its normal size.

Strangely, the trophy showing Puff Up in Super Smash Bros. for Wii U shows Jigglypuff at its large size, but retaining the original color of its eyes. When using the move during battles, Jigglypuff's eyes are yellow the entire time. Additionally, the pitch of Jigglypuff's voice and sound effects during the move is altered based on the speed of the match, which can be adjusted in Special Smash or Training Mode. Jigglypuff's Final Smash is the only one with this property.
