Super Dice Block
From the Super Mario Wiki
The Super Dice Block is Mario's special, red Dice Block from Mario Party: Star Rush. In Toad Scramble, when players have Mario in the party, he can roll a 0, 1, 2, 5, 6, or 7 to add to the player's total roll. This Dice Block can roll slightly higher than a Standard Dice Block, but it can roll a 0 to compensate.
