2D sprite of a businessman character in the style of classic Mario Bros gameplay. The character is designed to replace Mario, wearing a neon green and fluorescent blue suit, with a mustache, oversized shoes, and holding a small briefcase. The pose should be mid-action, like jumping or running in a side-scrolling game, with simple, pixelated, retro aesthetics. The background must be transparent, and the design must be flat and game-ready, as if directly pulled from a pixelated platformer game.
