The Bowser Express Train is made of 1,392 LEGO elements and includes interactive features such as a lever-operated spinning platform, a Super Star Block, a passenger wagon with a removable roof and “?” Block, and a cannon wagon with a spring-loaded cannon. Designed for kids ages 9 and up, the set will be $119.99.

“A lot of work went into designing The Bowser Express Train and ensuring it truly captures Bowser’s mighty presence and power,” says Daire McCabe, Design Master on LEGO Super Mario. “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.”

The next set unveiled for MAR10 Day is King Boo’s Haunted Mansion ($74.99). Builders can explore the haunted halls and interact with a Chest Block, Coin Block, and hidden Key Block with the 932-piece LEGO brick build. There are also popular enemy characters included. The set is designed for kids ages 8 and up.
