Greedy Dice Block
From the Super Mario Wiki, the Mario encyclopedia
The Greedy Dice Block is Wario's special, yellow Dice Block from Mario Party: Star Rush. In Toad Scramble, when players have Wario in the party, he can roll a 4, 5, 6, or 7 to add to the player's total roll, but the Dice Block has two -1 coin slots that can subtract one coin without adding any numbers to the total roll. A similar Dice Block is Waluigi's Risky Dice Block, where it can roll overall higher consistently but can subtract more coins as well.
