Well, it seems that this promo gave me a clearer view of the art style and makes it look a little less like Horrid Henry which airs on CN India quite a lot, but not a lot compared to other shows on other channels like Doraemon, Motu Patlu and now Bandbudh aur Budbak.
Thanks for the thorough reply. Yes, I meant the '80s cartoon. Hm. And you are 100% certain? Was there just one Canal+ feed in the '90s? And could have Canal+ been involved with TMNT in any way like distribution, etc.?
