Tropical Aquarium
10366-1 Icons 2025 4154 parts 6.5% catalog rarity Expert
LEGO Icons Tropical Aquarium (10366) builds an underwater display with four fish, coral and aquatic plants. Turning dials and cranks makes a fish swim, coral sway, a crab emerge from its cave and a treasure chest open. Sea worms, snails, bubbles and an oyster with a pearl supply smaller details around those mechanisms. The plants and creatures can be arranged to change the composition inside the tank. The finished aquarium combines a still underwater scene with manually operated movement for a shelf or desk display.
