Surrounding the submarine are multiple small bright yellow LEGO fish swimming at different depths, with several air bubbles rising upward in sharp detail. The seabed is made of LEGO bricks, including textured sand, blue tiles, and colorful coral elements in red, green, and yellow. The water is clear turquoise with soft light rays filtering from above, creating realistic underwater caustics and reflections.
