French dub found completely
From The Lost Media Wiki
I found it on a streaming web site called "ADN (animation digital network), but we have to watch the episodes, one after the other in order to have all of them. I can't access them, but they really exist on Internet : https://animationdigitalnetwork.com/video/779-nanooks
Otherwise, I found, on one of my VHS, a french bumper on french channel TF1 which I had filmed on my TV because I can't record the videocassette recorder : https://youtu.be/T4_XxVuhZA0
