I found this post on Tumblr from "klonoawahoonamco", with some Japanese text, and a very rough translation[生放送] 明日稼働開始の太鼓の達人 モモイロVer.には「The Windmill Song」が収録されています。奇しく1997年の同日には「風のクロノア door to phantomile」が発売されていました。
“The Windmill Song" has been recorded in the master pink Ver. Drumming running start [live] tomorrow. “Klonoa door to phantomile" was being released on the same day of 1997 odd correctly.
The fact that these guys still acknowledge not only the Klonoa series, but also his anniversary, makes me nothing less than happy; and I'm hoping that we can all find a way to celebrate it as well
