This may be a bit of a long shot, but what the heck.
I am trying to find any info on an animated music video from many years ago that parodied a bunch of classic space shmups (Ex - Gradius/Parodius). I believe it used the Vocaloid characters, animated in a video gaming 2D style, portraying them as members of some space fighter squadron and their mission hi-jinks. The music video ended with their cleaning robot back aboard their mothership accidentally triggering their super weapon and dropping a giant robot onto a city.
Anyone have any recollection of this? I cannot seem to find it anywhere.
