Back in 2015 I discovered an Easter Egg on the German Animal Crossing: New Leaf Website. It was Totakas Song. The Website was gone a few days later. I recorded it back then and uploaded it to YouTube. This is the only proof that this has ever existed. The website is not backuped anywhere on the internet. The video is the same as uploaded in 2015. I don't want to cut it to keep it original (that's why there is still a YouTube intro at the beginning).
