So here it is~nyo! http://www.panduck.com/media/flash/. Click c-song.swf.
The c-song-e (english version, I assume right now?) is squeaky.... o.O like chipmunks. Will watch the normal (non -e) version later.
And while you're there, check out hana_sing.swf. It's... reminds me of tellytubbies. Maybe someone who speaks or reads Japanese can tell us what it actually is, other than enhanced cuteness.
God, so many hyper flash thingies... *_* remind me later to watch them all and blind myself... Or put on sunglasses first or something.
