Do I need the Starter Course to use this set?

You can build and display the haunted yard on its own, but the tombstone and sensor tricks only activate once it is connected to a Starter Course with the interactive figure.

How many pieces and parts does the set have?

The set has 431 pieces made from 144 unique parts, mostly greys, reddish brown and white.

Does the set include minifigures?

No, LEGO® Super Mario sets use buildable models and an interactive figure instead of traditional minifigures, so this set has none.

Super Mario

King Boo and the Haunted Yard Expansion Set

This 431-piece LEGO® Super Mario expansion set adds a booby-trapped graveyard to any Starter Course. King Boo, the recurring ghost boss from the Mario games, anchors a scene full of wobbling tombstones and hidden triggers. It plugs straight into other sets in the range, so the haunted yard becomes part of a longer course.

Description

Built to connect

Like every LEGO® Super Mario expansion, this set is designed with connector studs on several sides so it can link up with other sections from the range, whether that is a Starter Course, a boss battle set or another expansion. Inside the graveyard, a tombstone flips, a branch springs out and a small platform spins once the interactive Mario or Luigi figure, sold separately, triggers the built-in colour sensors. That makes the yard less about static display and more about a course section with reactions built right in.

King Boo takes centre stage

King Boo, the oversized boss ghost from the Mario games, is the set's main model, built to move via a lever hidden in the scenery. There are no traditional minifigures here; instead the scene is told through buildable, poseable models and the separately sold interactive figure that reacts to the sensors as it passes through. For players who know the games, the set recreates King Boo's habit of lurking out of sight and popping into view when least expected.

A graveyard colour palette

The 431 pieces lean heavily on reddish brown, black and both shades of grey, with white picking out tombstones and small highlights, a palette that fits the spooky theme and sits well next to other Super Mario sets on a shelf. Among the 144 unique parts are plenty of grey bricks, plates and wall pieces that work just as well in general landscape or building projects once you move past Mario builds. The full parts list on this page shows exactly which elements are worth keeping.

Who this set suits

At 431 pieces this sits in the mid-size range for LEGO® Super Mario expansions, aimed at anyone extending an existing course with a themed section rather than starting from scratch. It can be built and displayed without the Starter Course, though the sensor tricks only work once it is connected to one. Fans of the graveyard aesthetic and moving mechanisms get a set that does more than sit still on a shelf, and works well as a gift too.
