A vibrant cartoon with colours and smooth animation. Create a colorful, cute 3D cartoon story for children about a beautiful green jungle during the rainy season. The main characters are a friendly little rabbit named Rumi, a clever monkey named Momo, and a small blue bird named Neeli. One morning, dark clouds cover the jungle and heavy rain begins. The animals are happy because the dry river is filling with fresh water. But suddenly, the rain becomes very strong and water starts rising near the animals' homes. Rumi the rabbit notices that a group of small animals is trapped near the river. Rumi, Momo, and Neeli work together to help them reach a safe, higher place. Momo finds a safe path through the trees, Neeli flies above the jungle and guides everyone, and Rumi helps the smallest animals cross safely. After the rain stops, a beautiful rainbow appears over the jungle. The river is full again, the trees look fresh and green, and all the animals celebrate together. The story should have a warm, magical, colorful children's cartoon style, expressive cute characters, beautiful rainy jungle scenery, gentle background music, natural character voices, and a happy ending. Add simple dialogue and narration throughout the story. The final message should be: "When we help each other, even the biggest problems become easier."
