The video captures an elaborate, underwater-themed display at the Moskvarium (Moscow Aquarium). The central feature is a large, illuminated scallop shell structure in pastel pink and white, bearing the golden text "Москвариум Русалочка любовь двух миров," which translates to "Moskvarium The Little Mermaid love of two worlds." In front of the shell is a large, iridescent pearl resting on a rock-like pedestal. The foreground and surrounding areas are decorated with numerous artificial coral formations in vibrant shades of pink, red, green, and black, resembling an ocean floor. The ground is covered with a light, sandy material. Overhead, several clear, spherical bubbles of various sizes are suspended, along with a prominent, orange-hued jellyfish decoration, enhancing the aquatic atmosphere. The background features a painted mural depicting underwater scenes with arches and marine life. The lighting is bright, creating a magical and immersive environment. A voice speaking Russian can be heard, remarking on the beauty of the display.
