Triple 7 Dice Block
From the Super Mario Wiki
The Triple 7 Dice Block is Diddy Kong's special, brown Dice Block from Mario Party: Star Rush. In Toad Scramble, when players have Diddy Kong in the party, he can roll either a 0 or a 7 to add to the player's total roll. It is similar to Donkey Kong's Brawny Dice Block, where it can roll multiple zeros, though it has fewer zeroes and lower numbers.
