Edit image 1 only: replace the small white short sword in the character's right flipper with the sword from images 2 and 3, "Grand Vision": a wide long straight blade of semi-transparent bright yellow crystal (#f8e81a) with jagged faceted crystal edges and a dark faceted polyhedral core inside, a thin yellow glow; a grey angular layered mechanical crossguard with yellow-green lines; a black ribbed grip; a mechanical pommel with a yellow-green fork-shaped ornament. Scale the blade to about 0.75 of the character's height, held low with the tip pointing down-right. Keep EVERYTHING else exactly unchanged: same pixel-art style, same pixel size, same colors, same pose, same canvas size and position. No glow halo, no extra effects.
