Figure Predictions

1 year forecast

$32.69

5 year forecast

$37.34

Weaker outlook

Stronger outlook

The forecast puts the King Boo figure at about $37.34 in five years. That is a softer outlook than most figures.

Prediction Insights

A brick-built King Boo figure tied to a single-wave release captured collector interest via its dark purple tongue variant, but recurring character iterations and recent softening in demand introduce remake risk and cap longer-term upside.

About Super Mario Expansion Set

The Super Mario figures are not minifigures but small characters built from a few bricks with printed faces, and many carry a printed code that the interactive Mario reads when he lands on them. The expansion sets bring the familiar enemies, Goombas, Koopa Troopas, Bob-ombs, Piranha Plants, Boos and Dry Bones, and friends such as Toads, Toadette and Yoshi in several colours.
