Says it worked in the original Dreamcast games, but even back then I don't recall whistling being a thing. It also said "flute" which I pressume it means the Mystic Melody, an artifact that does not show up until the next game.

I have a feeling whoever written that part on the SOnic Retro article had shenanigans in mind.
