How do I put this... I can't remember the name of the cartoon but its about a whale/
Shark who hates ships? All I can remember is the whale , black (most probably whale), hates ships and keeps hitting them with its head?

I don't think it's a famous cartoon , maybe even a failure , but I just want to see it for some reason.I watched it around mid 1990s - early 2000s.

Maybe,.

The Legend of the North Wind

Maybe,...

The Legend of the North Wind

Erm well, not quite thanks for the fast reply though.

And I am pretty sure it's a series cartoon , not a movie /film.

The whale is kind of an angry one, really angry, and its keeps on butting its head against a ship even though its size is really small compared to the ship.

That's all I can remember, ohya , its black on top and white on the underside ( the belly) like a killer whale.If its not black then a dark colour...
