Marine, Customer ServiceOh no! That's no fun. It’s rare for a LEGO® set to be missing a piece. If the wayward piece isn't just hiding on the floor or stuck in the packaging somewhere, we're here to help. Go to LEGO.build/BricksPieces-BV to request replacement part for your grandson! It will arrive in no time for him to complete his build.
