I vaguely remember this movie from when I was a kid.. it seems like I remember it being animated but it may have been a movie.. there was a unicorn that lived in some kind of cave which had some kind of body of water by it that was off a cliff.. there is a scene where the main character (I think a boy) has to jump into the lake and he can't get out for some reason..? Hope someone can help me.. I know it's not much information

I believe that movie is the last unicorn.

The Last Unicorn (1982)

annnd... if its not the last unicorn it may be the fantastic adventures of unico ^_^

I've been trying to find this movie I saw when I was extremely little about a boy who had three older brothers with really large magnificent horses, and they were pretty arrogant about them too, and the boy had a small mule looking animal, but it was really a unicorn. I remember they ended up leaving for adventure or something and they came to a village where a the boy fell in love or something so he has to prove himself and so he jumps into three cauldrons and emerges more adult and handsome... Idk what it is called or even when it was made, all I know is it is NOT THE LAST UNICORN!! I have seen that one too, and they are totally different movies. And I know it is not Unico because the unicorn didn't look like a deformed dog. So... if anyone remembers more... HELP! :)

Aha, I know what I was looking for; it wasn't a unicorn at all, just a small horse. It is magical though. So it is called Ivan and his Magic Pony. Not saying this is what you are looking for, I'm just saying in the event someone else who is looking for what I was will find it too and be happy like I am now!! :) This is an awesome site!
