Huevo de dinosaurio

// «Huevo de dinosaurio» · gpt-6-sol (medium)
// A giant cartoon dinosaur egg standing upright on z=0, oval and taller than wide, cream with green and brown speckles, with a zigzag crack across the top where a little green baby dino head peeks out with big eyes. It sits in a small ring of sand and pebbles.
