Pleasant Goat and Big Big Wolf is a full set of animated series. The story takes place in the Green Green Grassland during the Year of the Sheep, where the goat community has flourished with a small town, schools, supermarkets, and beauty salons. All goats live happily and peacefully. However, on the other side of the forest, Big Big Wolf and his wife Red Wolf can only drool at the sight of flocks of fat goats. Red Wolf realizes that leaving the wolf pack was the right decision made by her husband, but she wonders when he will cross over to bring back the fat goats for her to taste the grand goat feast.
When Big Big Wolf reappears before the stone bridge, young goats like Pleasant Goat, Pretty Goat, Boiling Goat, and Lazy Goat truly witness from reality the ugly appearance of wolves as recorded in books. Just like Wu Dalang (a character in another story), Big Big Wolf also finds it impossible to cross the iron fence. To prevent Big Big Wolf from playing any tricks, the village elder Slow Goat assigns the smartest goat in the village, Pleasant Goat, to guard the bridge.
Initially, Big Big Wolf thought that if he could destroy the iron fence, he could catch the fat goats easily. But every time, Pleasant Goat secretly tampered with the fence, causing Big Big Wolf to return home battered and bruised, with a gray face. In his heart, Big Big Wolf hates Pleasant Goat the most, who shows no respect for the dignity of the wolf pack. Every time, Pleasant Goat causes him great harm. Therefore, Big Big Wolf resolves to use every method possible to catch Pleasant Goat first to relieve his anger and pain.
However, Big Big Wolf doesn't know that his opponent is the smartest goat in the entire goat clan. Behind Pleasant Goat, there is the village elder and inventor Slow Goat, who appears foolish but is actually wise, Lazy Goat who loves sleeping but is strong as an ox, Pretty Goat who is beautiful and kind, and a large group of goat companions. Despite Big Big Wolf's continuous plots and schemes, he ends up suffering himself and failing in the end. Moreover, after returning home injured, Red Wolf does not comfort him but instead gives him a harsh scolding.
