Build Tips
Open bags one numbered sequence at a time — LEGO orders them to match the build stages and keeps loose piece counts manageable.
Budget 16+ hours across multiple sessions rather than one sitting. Fatigue leads to missed connections that are hard to trace later.
Keep the instruction booklet after building — it's the most reliable reference for disassembly, cleaning, or reassembly after storage.
Finding Instructions
With 5,255 pieces, set #2000400 comes with a thick instruction booklet — often split into multiple numbered bags and build stages. The official PDF is available free on LEGO.com, or use LegoFinder's AI to find it instantly from a photo.
