Build Tips
A five-minute sort by color or piece type before starting saves time hunting for specific bricks mid-step.
Follow the numbered steps in sequence — structural elements early in the build support everything that comes after.
For active play sets, key connection points (hinges, turntables, clip joints) can loosen over time — a small dab of LEGO's own tube clutch lubricant on the stud resolves most looseness without damage.
