Emily, Customer ServiceOh no! We're sorry to hear this. It’s very rare for a LEGO® set to be missing a piece. Usually you’ll find it stuck in the packaging, used in place of a similar piece, or hiding somewhere near your building area. If you’ve checked all over and the part hasn't appeared, don’t worry! It’s super easy to request a replacement. Just go to LEGO.build/BricksPieces to get started.
