DK Dock is a stadium playable in Mario Sports Mix. The playing area moves forward and backward, giving you more playing area, or less. The length of movement gets larger the longer you play. Eventually, the dock will move so much that a small area will open, revealing an opening to the water. In Basketball, if you dunk over the gap, you will fall in, losing nothing but gaining the points from the dunk. In Dodgeball, if you fall in, you are automatically out. In Volleyball, if you hit the ball into the gap, the other team gains a point.
