主持人：地球拯救隊製作

以趣味遊戲形式帶出不同環保訊息及香港的動植物資料，每集邀請一位小學校長及一位家長作嘉賓接受小主持挑戰。「雙長」須從66個「66無窮發聲遊戲」中選擇6項以動植物常識及環保觸覺破解難關。 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.
