Ok so I'm trying to remember anything about this movie that I just have a brief memory of. I watched it as a kid in the 90s but it could have been from before that. I just remember the part vaguely but there were these two dragon like animals that also swam in water and were together on this patch of land. It was a boy and girl and the girl was pink maybe? And was singing maybe? It's so vague but I can just remember this one part of the cartoon. Any ideas?

Oh and almost in a sweet way to the male to attract him I think
