I knew this! One of my favorite breeds of horse. Fjords are like teddy bear horses! I l was SO excited to see that they had them in the movie, since the movie was based out of Norway. A nice change of pace from the horses in most Disney movies.
My logic: Disney translated all of it. Because they wanted us to understand the movie. Also, Wall-e was left behind by the humans, he isn't from the future.<< But he IS in the future. The future from now to there.
