About LEGO Seasonal Halloween
Halloween is the Seasonal subtheme for LEGO's autumn sets of pumpkins, bats, ghosts and witches, and new ones arrive most years ahead of the holiday. The first sets of 2010 were small brick-built models with no minifigures at all, a jack-o'-lantern, a ghost and a bat, and the pumpkin has been rebuilt several times since.
2017 LEGO Sets
Two films anchored 2017: The LEGO Batman Movie and The LEGO Ninjago Movie, each with extensive waves and a dedicated CMF series. BrickHeadz moved from limited releases to a full collectible line, and LEGO Boost introduced approachable coding and robotics. Several short-lived lines from prior years, including the BIONICLE reboot and Mixels, were no longer active.
