About this set

This is Floating Otter, set 21366 from the LEGO Ideas line, a scene-category build with 1234 pieces in the inventory and a difficulty rating of 5/5, so it sits firmly in advanced-territory. The finished model is an otter in brown and beige tones holding a shell, floating on a trans-blue water base with green seaweed and white accents around the边缘. A sensible build order is to complete the trans-blue water base first, then layer up the otter's body, watching the brown-to-beige transitions in the instructions; save the forelegs gripping the shell until the torso is together so everything lines up with less clutch fiddling. The 5/5 difficulty comes mostly from the sheer volume of small-part stacking and the curved shaping, which makes it a solid pick for builders with plenty of experience who want an animal display set, while newcomers may want to start with the base to get a feel for the rhythm.
