I played KH2 a lot when I was younger to the point where my routine after school was to start a new game and beat it before bed.

I have this pretty distinct memory of being in the Twilight Town Tunnelway as Sora (in the area where you fought Vivi as Roxas) and hearing a very clear whistling sound. (like the one Pluto follows in one of the cutscenes.)

I've never encountered since that one time but just assumed it was a rare trigger in an area you never have much of a reason to visit, but I've watched a lot of blind LPs since and even looked up online and nobody else seems to have encountered it.

​

Has anybody else encountered this whistling or did I just imagine it? I live in Ireland, so I would've encountered it the original PS2 pal version if that makes any difference.
