3D Chibi-style Miniature of a Whimsical Lighthouse by the Seaside

Design a 3D chibi-style miniature of a whimsical lighthouse by the seaside, uniquely crafted to resemble a large seashell with a spiraling top and a glowing pearl accent at its peak. The structure features two levels, with round windows offering a clear view of the charming interior, which boasts nautical-themed decorations, soft blue illumination, and a mermaid-themed gift shop. Outside on the sandy beach, adorable little figures can be seen playing, lounging, or surrounded by beach accessories like towels and umbrellas, alongside tiny crabs scuttling about, adding to the delightful coastal ambiance. The overall design embodies a highly detailed, enchanting seaside aesthetic with a serene sunset glow bathing the scene in gentle light.
