I remember that I had a whole clip of behind the scenes of a lovable but mischievous penguin of south pole.
I downloaded a DVD rip of a 2001 release in Japan called "fun! fun! story ~ The Very Best of Pingu" from Emule, and eventually converted the whole thing to WMV file from May 2007. [And I'm sorry that the quality isn't really great as I converted it already]
So I hope you would all enjoy the featurette. :)
