Childrens' cartoons becoming popular. It's happened to quite a few. The ponies have just caught on much faster due to the controversy surrounding it. Either way, most western cartoons are written/drawn by the same small group or so, so if you like their work, there's a good chance you probably are into a variety of similar work. Bestiality isn't really a part of it at all.
what controversy is around this stupid show my 6 year old niece watches?
