Lego ~ Super Mario 71369 Castle Boss Battle expansion set buildable game 2020 *see below for what pieces are missing* Retired Unopened packs 3,4,5,6,7,8,9,10,11 are included ** Bag 1 and Bag 2 are not included/missing Google results: Based on the set's official step-by-step build order, the 2 missing bags contain the following standalone builds: Bag 1: The Dry Bones enemy figure, a mini lava catapult mechanism, and the foundational base layout for the front walls. Bag 2: The Lava Bubble enemy figure, the two front towers, and the left/right front wall segments.Because LEGO Super Mario builds are entirely modular, you can still build bags 3 through 11 right now! You do not need bags 1 and 2 completed to build Bowser, Boo, or the main center castle. They all connect at the end using standard plates Consider these cheaper workarounds: Skip the Front Walls: You can easily just play without the two small front decorative towers. The main castle experience is entirely in bags 6–10. Buy the Figures Individually: If you just want the missing characters, search for "LEGO Dry Bones mari03" and "LEGO Lava Bubble mari04" on eBay or BrickLink/ inexpensive. Use Bulk Bricks: The castle walls are mostly standard black, grey, and dark red bricks. Download the official Lego Builder App or visit the Lego instructions website. Age 8+ Starter course 71360 is required for game play and to play fully with interactive Mario figure (Mario is not sold in this set) Unlimited social or solo fun
