That video is actually genius. Think about it; it's not seemingly educational, and a pretty fun song for little kids. However, every memorable pairing has one thing in common: a first letter. This means that, by remembering the animal, they can follow up with the first letter of a color, then hopefully remember the remaining letters. This works because little kids naturally remember animals; it's like, a very interesting thing to them. It also works because they show the colors as well. So... yeah
