4-5-6 Dice Block
From the Super Mario Wiki
This special Dice Block could be obtained by landing on a Special Dice Block Space, a Lucky Space next to a Toad House or a Spin Space. The 4-5-6 Dice Block can be quite useful if there are Mini Stars ahead or if it would make the Captain land on a helpful space.
In Mario Party: Star Rush, the 4-5-6 Dice Block is only available in Mario Shuffle and can only be accessed with amiibo that do not have Mario Party 10 save data on it. It functions the same as in the previous two games.
