Late 80's early 90's anime movie
I saw this movie as a kid about a baby unicorn ( could have been a Pegasus) whose mother is beautiful and cloud like and floats him in the air and drops it off in the woods where he met a girl. The two set off on a journey and meet a young tiger along the way. In one scene they are on a beach where a giant rocking horse is placed. The unicorn crawls up the rocking horse and goes into the eye, leading to another world where an evil witch lives in a castle. The unicorn fights her, and the witch is crushed as the castle crumbles down. What is this movie called?! I've been searching forever and can't find anything.
