A whimsical 3D cartoon scene in Pixar style, showcasing a youthful trio of females. A curious young girl, with bright eyes and tousled hair, stands alongside her mother - a warm-smiling woman with a gentle expression. Together they gaze in utter disbelief at their grandmother - a sassy senior with a mischievous glint in her eye. The three generations are framed against a vibrant cityscape backdrop, with hyper-detailed buildings and bustling street life. Lighting is bright and playful, with a dash of humor captured in the exaggerated facial reactions and dynamic poses.
