Dr. Robotnik's Mean Bean Machine is a Sega Genesis puzzle game that reworked the Japanese falling-block game Puyo Puyo around Sonic villain Dr. Robotnik. Players stack coloured beans and clear them in lines, and the cheerful yippee marks one of those clears. The game became a cult favourite among retro Sonic fans, and clips from its sound effects later circulated on soundboards and in short videos. Its brevity and instantly recognisable retro tone keep it useful as a small, upbeat reward sound for wins, combos and jokes.
