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.
This Mom is super extra skilled - some of these are costumes for park workers, outfits you can't just pull up the movie and study the screenshots for. SO impressed! And, of course, the cuteness factor, I can't hardly stand it!
