LEGO Ideas 21366 Floating Sea Otter Rumoured For March 2026

The LEGO Ideas theme will start 2026 with a range of brick-built animal-centric sets, including the previously rumoured 21365 Love Birds and the focus of today's article, 21366 Floating Sea Otter. The latest 18+ branded LEGO set will include a total of 1,234 pieces retailing for $119.99 / €109.99 / £99.99. 21366 releases just two months after the Valentine's Day-inspired Love Birds on the 1st of March 2026, marking a much cheaper and unlicensed start of the year for the LEGO Ideas line.

21366 Floating Sea Otter is the latest brick-built character, droid, figure or animal seen in brick-built LEGO form in recent years. This time, it captures the semi-acquatic mammal reclining on its back in a relaxed, playful pose on top of a thin layer of brick-built water. The sea otter is coloured in multiple shades of brown, along with elements of tan being present around the animal's chest, belly and puffy cheeks.

Again, like many of the recent brick-built display models from an abundance of themes, the Floating Sea Otter has plenty of functionality and posability. The head in particular is full of character with those previously mentioned tan cheeks along with white whiskers, cute black eyes and an openable mouth containing a small but extremely cute pink tongue. The overall head can be spun around, along with plenty of movement in the otter's mouth.

Moving to the rest of the otter's furry body, both its front and back paws are fully articulated, allowing the carnivorous mammal to hold various brick-built animals whilst also giving a cheeky wave. The legs and tail extend naturally beyond the simple black base of the 18+ model, which is covered in transparent blue tiles representing the shallow water environment that otters are often found in.

In the water and covering the base of the model, we can find various elements of brick-built scenery. Various seaweed pieces and colourful leaves are floating around the otter alongside a small rocky outcrop in the corner, supporting mushrooms and further elements of colourful vegetation. A couple of transparent white pieces can also be found amongst all of the blue of the sea, recreating splashes, waves and bubbles in the extremely cute and calming 2026 LEGO Ideas set.
