I saw an animated movie when I was a kid (maybe in 1990-1992) that the main character was a duck (I think the theme was ugly duckling, or a duck that is lost and is trying to find it’s home, and I also think that it had french language).
The duck go through several locations. I rembember some tubes, a crocodile, and some house roofs.
“howard the duck ” by marvel maybe?
Crayola Presents: The Ugly Duckling, although that is in english has no crocodile and was 1997. Also its about a swan, thought i’d throw it in their anyway just in case.
