Part # 4243838 (brown 4 row x 4 row flat square)

You need 3. I’ve got 3 , but one is broke. See photos

Part # 4211225 (brown4 row piece )

You need 3. I’ve got 2. But I added a black piece replacement.

No box

All other pieces and mini figs are included. Plus manual. I’ve counted and went over parts list twice. So I’m 100% sure technically you would need two pieces to complete this correctly. But with the added black piece. And even the broken piece will work. As it matches up perfectly. See last photo. You can’t even tell it’s broke.

Please ask any questions you may have ! But with confidence! Awesome set of 4 mini figs. They are worth my asking price by themselves! Thanks.
