Coinado

The Coinado is an item from Mario Party: Star Rush. Like the Fling Spring, this item can be placed on the board in a similar manner to orbs and hexes from previous Mario Party games. After being placed, the Coinado is invisible to all other players until a player lands on this space, which can include the player who placed it. Whoever lands on it is spun and loses five coins to the player who placed it.

The Coinado returns in Super Mario Party, as an item the player can use directly on an opponent rather than a stage hazard. It also has the chance of stealing ten coins instead.
