Super Mario Galaxy 2 arrived on Wii in 2010, continuing Mario's planet-hopping adventure with new power-ups and gravity puzzles. Inside its files, the coin pickup cue was stored as CS_COIN in the SpkRes archive, and in play it was sent to the Wii Remote speaker instead of the main speakers. That unusual placement is why fans extracted and shared it separately, and why it still appears in gameplay videos, memes and retro Nintendo edits as an instantly recognisable reward sound.
