This creepy song reminds me of why I have never been keen on trickery – which is why I detest this American idea of the similarly-named 'trick or treat' activity that we seem to have permanently imported into Britain in recent years, especially for this particular day of the year.
As in this item, there is always the threat ('treat' with an 'h' added, notice!) of something nasty being done by someone who has temporary power over you, whether on your doorstep or having drugged and then blindfolded you deep in the forest. Follow the subtitles to see what I mean.
I am reminded by this kind of scenario of the advice that the lady who jointly ran Byker Grove youth club with Geoff would say to her female charges: "Never let anyone put you in a position where your choices are taken away from you".
This jolly-sounding but actually quite ominous song is a good showcase for the Kagamine duo in its own right, so can be enjoyed on that level. Just don't forget the underlying message carried within it...
