It was like 2014 or 2015 I first saw the video. The video was basically a compilation of short kirby animations while Caramelldansen would play. After a couple of years the video was deleted and it was only archived once in the Wayback Machine, though unfortunately Adobe Flash Player was discontinued making the video lost. web.archive.org/web/20140501053955/https://www.youtube.com/watch?v=c3_EfHhc8ic
However, one day I saw a video called "My Favorite Kirby Shorts!" on my recommended, and the video in its entirety played during the end. The video is very late 2000s and I find it charming in that way.
