Get That Crown!
From the Super Mario Wiki
In Hyde Park, players need to get a crown and keep it away from the others. The crown starts in the center and is gotten by getting it or tagging the player with it. Players who get the crown can't be tagged within the first three seconds of having it. The player with the crown at the end of the minigame time of 45 seconds or keeps it for 15 seconds without being tagged wins.
