A whimsical, ultra-detailed 3D illustration of a cute toddler girl with an oversized head and big expressive eyes, standing barefoot inside a white bathroom sink. She is balancing on a giant toothpaste tube while brushing her teeth with a blue toothbrush. Water splashes everywhere, frozen mid-air in sparkling droplets. The child has dark brown hair tied in a messy bun with colorful hair clips, wearing a loose gray t-shirt and patterned shorts. Soft natural morning light streams through a window, creating a clean, cozy bathroom atmosphere. Pixar-style character design, chibi proportions, hyper-realistic textures, shallow depth of field, bright pastel colors, playful and joyful mood, ultra-high resolution, cinematic lighting.
