The three little pigs, Big Treasure, Second Treasure, and Third Treasure, were going to build houses. Lazy Big Treasure chose to build his house with straw because it required less effort; equally lazy Second Treasure chose to build his house with wood because it didn't take much more effort to build a sturdy house; only the industrious piglet Third Treasure chose to build his house with bricks because it was the strongest. The houses were built, and the big bad wolf came. As a result, the older brother's house fell easily, and he ran to the second brother's house. The second brother's house also could not withstand the attack of the big bad wolf, so Big Treasure and Second Treasure fled into Third Treasure's house. The brick house no longer feared the big bad wolf, and Big Treasure and Second Treasure then realized their mistakes.
