地球孩子为两只老鼠庆祝婚礼；联合国秘书长接见外星鼠；在雷欧的哭声中,一个崭新的时代到来了。在思维波发射器被龙博士摧毁的那一刻,世界各地的老鼠像落潮的海水一般溃退,钻到地下,消失得无影无踪。地面上到处是肮脏、发臭的老鼠尸体。人们开始打扫战场。装甲车、坦克、陆军开始撤离海拉市。狮皮龙市长望着市政府的废墟,既后悔,又庆幸。他后悔没有早听龙博士的话,庆幸自己及时采取行动。 Earth children celebrate the wedding for two mice; the UN Secretary-General interviewed alien rats; a new era has come in the cry of Leo. At the moment when the thought wave launcher was destroyed by Dr. Long, mice all over the world generally retreated like the ebb and flow into the ground and disappeared without a trace. The dirty, stinky rat's body was everywhere on the ground. People began to clean the battlefield. Armored vehicles, tanks, the army began to withdraw from Hela city. Mayor Lionel Pisces looking at the ruins of the city government, regrettable, but fortunate. He regretted not hearing Dr Long earlier, but fortunately he took timely action.
