This article refers to a glitch in Super Smash Bros. Melee.
As Bowser lands from the air dodge, his right hand (the one holding the capsule) will quickly grow to many times its normal size, then just as quickly shrink back to normal. It grows and shrinks over the space of only a few frames, so it is difficult to pause the game at exactly the right point. If the game is paused when Bowser's hand is giant, inspection reveals that the giant hand is as detailed as Bowser's normal hand. It can also distort platforms.
