Bright 3D cartoon for toddlers, underwater scene: three cute dolphins singing together — one red, one white, one blue. Their mouths open and close rhythmically as they sing, their eyes are large and alive with shiny highlights and expressive blinks, not flat dots. Colorful coral reef and bubbles, cheerful kids animation style, smooth camera, high quality cartoon rendering.
