Puff Up glitch
This glitch in Brawl is performed when a player controlling Jigglypuff gets a Smash Ball. The glitch works on any stage where terrain is regenerated (like the awnings on Onett, the floor on Green Hill Zone, the hole in the Bridge of Eldin, when the king of red lions comes on great sea, etc). On the Bridge of Eldin, After King Bulbin destroys the middle of the bridge, the sky will turn dark. When the sky turns light again, black specks drop down. Right as they start falling, jump into the space where the Bridge will re-appear with Jigglypuff and use her Final Smash. Jigglypuff will start to grow, during which the bridge will be fixed, and if timed right, Jigglypuff will be launched into the air and will stay in her larger state. On Great Sea, the Final Smash must be used on the right hand side of the stage just before the King of Red Lions arrives, so Jigglypuff gets stuck between the ship and the King of Red Lions. She now has a larger attack range, but her damage will remain the same. Additionaly, if Yoshi (or Kirby with Yoshi's ability) uses egg lay on Jigglypuff while she is in her permanantly inlarged state, she will escape the egg and become twice the size she was before. To end the glitch, just self-destruct or use a Final Smash again.
