Create a 3D digital illustration in a cartoon/animation fantasy/whimsical style. The scene features a serene and enchanting forest at twilight, with a cute, smiling snail as the focal point. The snail has a shimmering, blue crystalline shell and expressive, sparkling eyes. It is surrounded by delicate, glowing fireflies and enchanting, softly glowing flowers. The background includes tall, majestic trees and lush foliage, bathed in the warm, gentle light of the setting sun. Butterflies flutter around, adding a magical and whimsical touch to the serene and soothing atmosphere.
