康樂及文化事務處《校園幹探易合一 之 秘密花園之謎》"School Detective 2 in 1 - The Secret Garden"

大細路小學3D班班主任吩咐同學們為新學期的壁報設計主題「氣候轉變」作分組資料搜集比賽。笑妹妹與呂同學從網上找到過千個相關網站；多士妹與藍同學從圖書館借出有關氣候轉變的書籍；阿明及星仔決定做一個以「海嘯沖擊下的亞洲」為題的模型等等……。與此同時，亞明家後花園的白楸樹卻無故枯死。正當大家七咀八舌地討論時，一向有偵探頭腦的校園幹探易合一卻以靜制動，經過再三思考後，最終帶領一班同學合力解開這個「秘密花園之謎」。

Jumbo Kids Primary School Class 3D is now having a display board decoration competition on the theme “Climate Change”. Smiley and Ah Lui find thousands of information on the internet. Toasty and Ah Lam borrow a bunch of books from the library. Ming and Little Star work on a model based on “The Asia under the devastating tsunami” while Clear-minded 2 in 1 decides to start with things happening around him. He believes the actions of tackling climate change should be started at home.

The story begins as 2 in 1 invites all his friends to investigate on the death of a Mallotus paniculatus (a fast-growing native evergreen tree) in Ming’s backyard.
