Whispy blink glitch
The Whispy blink glitch is a glitch in Super Smash Bros. Melee, first discovered by Magnus420 on SmashBoards. The glitch does not exist in the PAL release of the game and version 1.0 either.
How to perform
The player must choose Marth or Roy in a Versus Mode match or Training Mode and choose Dream Land as the stage, and wait until Whispy Woods blinks. On the last 2 frames of Whispy Woods blinking, the player must execute a jab, forward tilt, up tilt, down tilt, dash attack, or standing grab. Marth or Roy will swing their sword in a unusual way, and the hitboxes for these attacks (sans standing grab) will disappear until the move finishes. As for the standing grab, Marth or Roy does the grab without lunging forward, making it safer than a normal grab. However, this method is somewhat inconsistent.
Explanation
The mechanics of the glitch are unclear. One explanation provided by Evsen on reddit on September 2016 stated that when he was using Dolphin emulator's texture dumping feature and claimed that Marth's face was dumped on Whispy Woods. He assumed that Marth and Roy's blinking animation is tied to Whispy's, and the animation glitches because the game may have been trying to use both blinking textures at the same time. Though accepted for years, AsumSaus debunked it in 2020, who analyzed Evsen's footage and could could not recreate the blinking textures, making AsumSaus believe that Evsen might have misremembered exactly what happened.
