Playful Pegasus in a Dragon's Glittering Lair

Cartoon-style pegasus with a white body, rainbow mane and tail, big sparkling eyes, small wings, floating gracefully inside a dragon's lair. A friendly dragon with emerald-green scales lounges in the background near a treasure hoard of gold coins, gems, and glowing crystals. The cavern glows with warm gold light from the treasure and cool blue-purple glow from crystals. Bold outlines, flat vivid colors, and cute, expressive features in a playful, kid-friendly cartoon style. Composition centers on the pegasus near the treasure, with the sleepy dragon watching softly from the shadows. Lighting is whimsical with soft gradients and cel-shaded shading to enhance the cheerful fantasy mood.
