This is the advent calendar filled with delightful LEGO City surprises that builds excitement during the Christmas countdown as a child builds each day’s toy. Each of its 24 doors opens to reveal a detailed construction toy that sends kids on fun imaginary adventures as they build vehicles such as a snowplow, a trolly, and a holiday train, sing carols around a snow-covered Christmas tree, or play ice hockey on a frozen pond. Each surprise toy comes with easy-to-follow building instructions ensuring that even new LEGO builders can enjoy a fun build-and-play experience. The 349-piece set can be arranged on the flip-down snowy city play mat or combined with existing LEGO toy playsets.
