A vibrant cartoon with rich colours and smooth animation. Shadi is a small, energetic, curious brown bear wearing a red cloth hat. Lin is a small, calm, wise white bear carrying a small backpack. Grandfather Hudhud is a wise hoopoe bird wearing small reading glasses, with a warm voice. Golden sunlight filters through the branches of lush green trees. Shadi happily jumps between the branches while Lin sits under a tree reading a book. The camera begins with a wide shot showcasing the beauty of the magical forest, then moves closer toward Shadi and Lin. Birdsong and cheerful, gentle music play. Shadi says enthusiastically in Arabic, "يا لين! انظري إلى هذا الطقس الجميل إنه يوم مثالي للمغامرة!" Lin smiles and closes her book, saying in Arabic, "بالتأكيد يا شادي ولكن أي مغامرة تقصد؟ لقد استكشفنا كل شبر في الغابة!" Suddenly, a large branch shakes and something wrapped in old leather and tied with a gleaming golden ribbon falls down. A soft falling sound is followed by a magical sparkling sound. Shadi jumps slightly in surprise, then approaches and says in Arabic, "أوه! ما هذا الذي سقط من السماء؟" Lin cautiously approaches and examines the object, saying in Arabic, "تمهل يا شادي... هذا ليس غصناً عاديًا إنها لفافة قديمة جداً!" Shadi excitedly opens the scroll, revealing a colourful map with winding paths, a glowing tree, and a drawing of a golden key at the Lake of Secrets. Cut to an extreme close-up of the map and Shadi and Lin's eyes widening in surprise. Suspenseful exploration music plays. Shadi says in Arabic, "لين! هذه خريطة كنز! انظري تهدي إلى بحيرة الأسرار!" Lin points at the map and says in Arabic, "ولكن انظر هنا يا شادي... هناك لغز مكتوب بالأسفل ويقول: لن يعبر الجسر إلا من يعرف السر!" Shadi says in Arabic, "مستعدون للمغامرة؟ لننطلق الآن!" They carry the map and start running toward the path leading deep into the mysterious forest. The shot ends with a sudden stop before the first obstacle: the River of Moving Stones. Voice-over in Arabic asks, "ما هو السر الذي ينتظر شادي ولين عند النهر؟ وهل سينجحان في عبوره؟" The suspenseful music builds, followed by a short energetic musical note.
