Star Block (Mario Party DS)
From the Super Mario Wiki
The Star Block is a rare type of Hex in the game Mario Party DS. The player who possesses it can choose to place it on any Blue Space or Red Space within five spaces from their current location. Then, if anyone lands on it, a Dice Block appears with the numbers 1-3 on it. The player then strikes the block, receiving the amount of Stars indicated. You can get it in a Hex Area or receive it re. the Snag Bag.
