Lightning Score Striker
From the Super Mario Wiki
The Lightning Score Striker (-3 Lightning in the British English version) is an item found on the Perilous Palace Path board in Mario Party: Star Rush. These items can be won from getting first place in minigames and selecting the item. When used, it shocks the opponent and subtracts 3 from an opponent's dice roll. If the opponent rolls low enough, they cannot move. Its opposite counterpart is the Dash Mushroom, which adds 3 to the user's dice roll.
