About LEGO Floating Sea Otters
Sea otters are known for their endearing habit of floating on their backs while holding hands to avoid drifting apart. This 1,234-piece LEGO Ideas set captures that gentle behaviour with a detailed model of a mother otter and her removable pup.
The build centres on a poseable mother otter figure with articulated head, mouth, arms and flippers. The baby otter can be positioned on her belly in the classic floating pose, or the mother can be displayed holding a brick-built clam instead. The model measures 30 cm wide, 19 cm deep and 8 cm high when complete.
Building Experience
This set offers a mindful building experience suitable for both newcomers to LEGO and experienced builders. The model forms part of the LEGO Ideas collection, where fan-designed concepts are voted on by the LEGO community before being produced.
The finished piece works well as home décor, capturing the calm and peaceful nature of these marine mammals in a display-worthy format.
