Sea Animals

The LEGO® Sea Animals (set 31158) is a 421-piece LEGO Creator 3-in-1 set released in 2024, packing three rebuildable underwater scenes into a single box. The first build assembles two fish, a turtle, a jellyfish, a seahorse, and a red crab onto a seafloor stand of sea plants connected with transparent rods; positions can be swapped and the stand straightened or angled for display. The same bricks rebuild into an octopus and squid beside a piece of bubbling volcanic rock, or two fish gliding through colorful sea plants. A versatile ocean-themed Creator set whose transparent display rods give every figure a sense of mid-water motion.
