LEGO® 創意百變系列 3合1 海洋動物：美麗海豚 31385

The tail articulation on the dolphin is surprisingly smooth, so my son kept flipping it through pretend waves for an hour. We’ve only finished the first build so far, but the fact that it can transform into two other sea creatures makes it feel like three sets in one.

My daughter built all three models over a weekend and the shark was definitely her favorite, the fins move really smoothly. The dolphins look so lifelike on my shelf now, I love the way the tail articulates.

Took my 10‑year‑old about an hour to build the dolphin, and the fins click into place with a satisfying snap. Only reason it's 4 stars is the shelf space needed if you want to display all 3 builds separately.
