well, these isn't actually MLP related, but it's called Pony Tale. It's free movie from Action Horse Films,featuring world wide riders. Yes there's pony character (looks more like horse) in it. and I don't think they had MLP in mind because it was made in 2007, way before MLP:FIM it's been my favourite snowboard movie of all times. here's the full movie. enjoy [video=vimeo;2088857]http://vimeo.com/2088857[/video]
