Kangaroo Called LJ

When LJ and his friends jumped the neighbour's fence and started to eat his grass, he was frightened one day by the farmer saying he would get his gun and shoot them if they ever came back and ate his grass again! But a few days later when the herd of kangaroos was hungry again for fresh green grass, and jumped the farmer's fence, LJ and some of his friends were hurt when the farmer brought out his gun and aimed it at them! Did the farmer shoot any of the kangaroos? And did he keep doing it or did he think twice about the dangers of guns?
