Bowser Dice Block
From the Super Mario Wiki
A Bowser Dice Block is a Dice Block appearing in Mario Party: Island Tour. It only appears in Bowser's Peculiar Peak. The player can get bonus Bowser Dice Blocks by placing 2nd (Bronze), 3rd (Silver), or 4th (Gold). These may hinder the player when they are rolled, or if doubles are rolled, they will stay where they are. In Mario Party 10, Bowser uses four of them to move from space to space to catch up to Team Mario. At the halfway mark, Bowser fuses all four to make the Super Bowser Dice Block, a dreadful version of the Bowser Dice Block, which when it lands on a Bowser mark causes Bowser to instantly catch up to Team Mario, making the game more challenging.
