“71377 King Boo and the Haunted Yard Expansion Set is a good set in the theme, with a nice central mechanism and visually offering more than most. Those who are committed to collecting this theme will be doing so knowing that the value isn't great, for most though, the price... More tag will put them off this set.”

The Rambling Brick
“This is another interesting, goal directed expansion set for LEGO Super Mario. The mechanisms and bonuses are fun to activate, although it is disappointing that the 5 coin bonus tiles are identical – as the game will only allow that sticker to be scanned once during the... More game.”
