Natasha, LEGO® Customer ServiceOh no! We're sorry your build isn't going as planned. It’s unusual to have pieces that don't fit, so just in case, I’d recommend double-checking that you haven’t accidentally swapped these with a similar part or missed a step in the instructions. If your set does have the wrong parts, then we’re here to help. Get in touch with us via LEGO.build/Service-BV and we'll be happy to troubleshoot your build.
