“Rather than a rainforest, 40783 recreates a vibrant and colorful Coral Reef in brick-built microscale. In the 12+ display model, we can see the Coral Reef covered with different plants, fish and sea creatures. Some of the more obvious brick-built marine life include a... More starfish, a crab and a jellyfish that glows in the dark. Plenty of interesting building techniques and recolors are included in the latest promotional item available in April.”

“The set itself is made up of 260 pieces, including some suitably brightly colored elements to make up a LEGO coral reef. It’s also filled with marine wildlife, including a glow-in-the-dark jellyfish, as well as crabs, starfish, and other life from under the sea.”
