Billund, March 11, 2024: Over the weekend, the LEGO Group celebrated MAR10 Day (March 10th) by unveiling three incredible new LEGO® Super Mario™ sets – The Bowser Express Train, King Boo’s Haunted Mansion and Battle with Roy at Peach's Castle – and confirmed that the globally-loved Mario Kart™ will be coming in LEGO brick form next year!

Every year on March 10, fans from all around the world mark MAR10 Day by celebrating their favourite Super Mario characters. This is the second year that the LEGO Group has held an action-packed YouTube premiere for MAR10 Day. Jack Gardner hosted the celebrations and was joined by a playful family of LEGO Super Mario fans, who helped add some extra mischief and fun.

New Iconic Builds Announced
Fans were delighted to see that not one, not two, but THREE new products were added to the LEGO® Super Mario™ universe, each specially selected to allow builders to expand their play adventures and join in on the endless fun.

The first set revealed was The Bowser Express Train made of 1,392 LEGO elements, created by Marvin Völger, concept designer, Daire McCabe as the model designer, and Amy Bennett, interaction designer on LEGO Super Mario. This set invites thrill seekers to jump aboard the locomotive for fun adrenaline-filled play. Packed with interactive features, including a lever-operated spinning platform, Super Star Block, passenger wagon with removable roof and “?” Block, and even a cannon wagon with a spring-loaded cannon, there’s plenty of play options and secrets for builders to enjoy.

Daire McCabe, Design Master on LEGO Super Mario said: “A lot of work went into designing The Bowser Express Train and ensuring it truly captures Bowser’s mighty presence and power. We wanted to create this epic set, inspired by the iconic train level in Super Mario 3D World, where Mario shoots out of a cannon to take on all the enemies on the train – capturing the spirit, energy and adrenaline of the original game. I can’t wait to see everyone’s reactions!”

Next up was King Boo’s Haunted Mansion with 932 LEGO bricks. In the YouTube premiere, the family were left in a pitch-black room and found LEGO® Luigi™ and a Yellow Baby Yoshi, then showed off their skills by defeating a Dry Bones. Throughout the segment, the set’s play-packed features were explored including the haunted halls, which featured a Chest Block, Coin Block and hidden Key Block for interactive play. The Haunted Mansion allows builders to use their spooky imaginations and go on a mysterious adventure packed with elevating furniture, well-known enemy characters, and more.

Last, but certainly not least, was the Battle with Roy at Peach's Castle made of 738 LEGO elements in total.

The castle features a catapult, easy-to-rebuild walls and boasts a beautiful interior, including a rotating throne, a piano, and fountain in the garden.
