Brick or Treat this Halloween with Lego

Summer seems to be fading fast, but never fear; it just means that Halloween is around the corner! So as the evenings draw in and the leaves start to change, why not check out some of the Spooky Lego builds we have here at Chaos Cards. Each set makes for a fun activity to enjoy on your own or with family and friends and add a little spooky spirit into your Halloween celebrations. From a haunted mansion with all the trimmings to a creepy barn filled with secrets, we think these sets are sure to delight. So, get ready to build and play... if you dare!

 

Lego Creator 3in1 Haunted Mansion (31167)

Lego 3 in 1 haunted mansion[1]

Are you looking for a truly spine-chilling Lego building experience this Halloween? The Lego Creator 3in1 Haunted Mansion (31167) might be exactly what you need! This two-story haunted house is filled to the rafters with spooky details, including a graveyard, a spooky tree, and an organ. Turn a wheel to reveal a hidden ghost, or open the back to discover more ghoulish surprises! We love that the Haunted Mansion is fully interactive and you can customise many aspects of the Mansion.

This set isn't just one build—it's three! You can use the same bricks to build either the haunted mansion, a haunted ship, or a haunted train set. Each model comes with five minifigures, including a werewolf, a vampire, Frankenstein's monster, a skeleton, and a ghost with a glow-in-the-dark cape. The 3 in 1 set offers plenty of opportunities for creative and imaginative play once built. Talk about a fun way to act out any spooky stories this Halloween!

 

LEGO Super Mario King Boo’s Haunted Mansion (71436)

Lego Halloween Super Mario Haunted House[1]

If you like your Haunted Mansions to be related to Super Mario, why not check out the Lego Super Mario King Boo’s Haunted Mansion (71436)? This adventure playset is made up of a haunted house, with the added bonus of some of your favourite Super Mario characters. There’s a Yellow Baby Yoshi, a Dry Bones, a Boo, and even the big boss himself; King Boo. (If you already have Lego Mario, Luigi, or Peach figures, you can use them to add to the fun and collect even more rewards, defeat enemies, and help find the key to the treasure chest.)

We love that once built, the mansion opens up for easy access, it makes a great playset for younger Lego builders to play creatively. Inside reveals a spooky elevating sofa and even a bookcase with a hidden key. King Boo's Haunted Mansion is perfect for gamers who love Halloween and offers a new way to explore the ghoulish side of the Mushroom Kingdom.


Lego Halloween Barn (40721)

Lego Halloween Barn[1]

Enter…if you dare! Let yourself get creative with the Lego Halloween Barn (40721). This spellbinding and creative Lego set is perfect for kids aged 8 and up, and is PACKED with fiendishly, ghoulish details.

Halloween lovers will love building this creepy, run-down barn before discovering all it's thrilling details hidden inside. Discover hidden teeth behind the door, a spooky bat and lamp, and fun decorations. A skeleton minifigure brings the magic to life, providing hours of imaginative play. Once the spooky fun is over, we think the barn makes an enchanting addition to any Halloween display!
