LEGO SET 31130 - Alternate build | Sunken Treasure Mission
Title: Dive Into Creativity — LEGO Set 31130-1 Sunken Treasure Mission Alternative Builds
When you pick up LEGO Set 31130-1 – Sunken Treasure Mission, you’re already invited on an undersea expedition. But what if the adventure didn’t stop there? What if your submarine could transform into a robot warrior, a beetle, or even a Christmas reindeer? That’s exactly what the world of alternate builds offers—a way to unlock entirely new possibilities using just the same bricks that come in the box.
The original set provides a submarine, a mechanical crab, and a diver—three builds that are full of underwater charm. But the Creator 3-in-1 format is only the beginning. Creative minds on Rebrickable have taken this set and reimagined it in wildly different forms—spanning from sci-fi to seasonal, robotic to organic, whimsical to action-packed. Whether you're into Transformers, sea creatures, futuristic tech, or playful creatures, there's an alternate build that speaks your language.
So let’s explore the vibrant ocean (and beyond) of possibilities that lie within this modest box of bricks.
