Hidden Block (Mario Party series)

A Hidden Block is a block that contains coins and random items in the Mario Party series. Its appearance changes with each game, sometimes resembling Brick Blocks, other times looking more like a small Treasure Chest. They only appear after landing on a space. It can give out anywhere from 5 to 20 coins or give out items such as Skeleton Keys, or even Stars. Mario Party DS features an one-time use item called a Block Sensor that makes a Hidden Block appear on the space the player lands on after using it.

Trivia

 * A Capsule similar to Hidden Blocks called the Coin Block Capsule appears in Mario Party 5. Like Hidden Blocks, they reward money, but unlike Hidden Blocks, their location is set on one space and visible to all.
