The 1-2-3 Dice Block is a special item which first appears in Mario Party 9 and reappears in Mario Party 10. It can be obtained by landing on a Dice Block Space or Spin Space. It can be also found in the Toad House.
The player can use it to roll from 1 to 3. The Scaredy Rat used this Dice Block in the Captain Event of Boo's Horror Castle. Bowser gave the captain the 1-2-3 Dice Block leaving it with its bad luck in the third Captain Event of Bowser Station. It was also used in the two Captain Events of Blooper Beach by the player's choice.
