    One of my favourite cartoons are Pleasant Goat and Big Big Wolf. I have seen many cartoons. Because Pleasant Goat and Big Big Wolf is my favourite. I like it because it's much modern than another cartoons. The story is about a clever goat. It is the hero of the story. It's clever and brave. It always finds ways help other goats run away from Big Big Wolf. It leads other goats fighting the Big Big Wolf. They protect each other and work hardly together and they are always successful. The cartoon is very interested. I can't always help to laugh. If you haven't saw it yet, please don't miss it.
