Let's hear it for youtube, reminding me of another childhood memory. I'd forward the link but I wouldn't wish my dissapointment on anyone else, you see they have it up in chapters 1 through 10 and chapter 9 refuses to load.
The little unicorn (who admittedly seemed more like a puppy than a pony) was sickeningly sweet, to be sure, but it was amazing how much effort the old Japanese animations contained when compared with Disney resources.
Word is they will be releasing an official DVD soon. Look for it.
