Build Tips
Check the piece count on the bag against the parts list before starting — knowing what you have prevents mid-build surprises.
Even in small sets, connection order matters. Follow the steps rather than building sections independently.
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.
