主持人：地球拯救队制作

以趣味游戏形式带出不同环保讯息及香港的动植物资料，每集邀请一位小学校长及一位家长作嘉宾接受小主持挑战。「双长」须从66个「66无穷发声游戏」中选择6项以动植物常识及环保触觉破解难关。 The programme brings forth in the form of interesting games, conveying different environmental protection messages and information about animals and plants in Hong Kong. In each episode, a primary school principal and a parent are invited as guests to receive challenges from the child presenters. The “two seniors” have to select six items from the “Game of 66 Voices”, and solve the problems by common senses about animals and knowledge about plants and environment.
