A group of little pigs were pushing stones across a bridge. It was very difficult for them to get on the bridge and they needed to work together. But at this time, one little pig took advantage of the busy time of the other pigs and kicked the little pig beside it into the river. After some time, it informed the other little pigs that one of them had fallen into the water. One of the little pigs happened to see the scene of the fall, but it didn't look carefully~
