Kids 3D thumbnail style

Glossy 3D nursery-rhyme world: round big-eye characters, candy pastels — Cocomelon energy.

What this style looks like

When you pick the Kids 3D style in Thumby, the AI agent assembles every render around these visual rules — the same prompt scaffolding our system uses to build a CTR-tuned thumbnail in roughly 60 seconds:

soft-shaded 3D family of toddler-aged characters with oversized round heads, huge sparkling eyes and tiny rounded limbs, simple pastel toy props (school bus, blocks, instruments) arranged around them, no text overlays baked into the art

Color, lighting, and mood

warm sunny daylight, candy pastel palette of butter yellow, mint, soft pink and sky blue, bouncy rounded shapes, every surface slightly glossy, pure wholesome cheer with zero peril or shadow

Composition rules

On top of the look itself, every render in this style follows these layout principles — tuned to keep the thumbnail readable at mobile-feed size and to maximise CTR on YouTube’s 2026 algorithm:

characters lined up smiling directly at camera anchored on the lower two-thirds, a single hero prop or vehicle slightly behind them for scale, sky-blue gradient backdrop with soft cloud puffs and clear room across the top for a song title

Who this style is for

Pick the Kids 3Dstyle when your video lives in the niche this look was tuned for. Most users pair it with a one-line topic — the AI agent writes the full prompt, applies the style on top, and ships a 16:9 thumbnail you can download or upscale to 2K / 4K straight away. If you’ve got a face or product photo to anchor the render, drop it in as a reference and the style renders your subject in the look above instead of a generic stock figure.
