Bowser Jr. Blvd.

Bowser Jr. Blvd. is one of the fourteen courts that appears in Mario Sports Mix, and is used in three of the four sports; it is not used for Dodgeball. The court is located in an animated, very illuminated boulevard, on a giant screen ground.

In Basketball and Hockey, icons appear on the ground and modify the points obtained according to what is written on them if the player scores while they are placed on one of them. Blue icons represent positive values and multipliers, red means negative values and green gets progressively smaller. Some of these icons can move. Twice in each period, the ground is illuminated for 15 seconds, and multiplies the base points by 10 if the player scores during this time (For example: If a three-point shot is made, seven coins have been collected, and the screen is illuminated with a ten times multiplier, then that team gets 100 points). Whenever their team scores with a special icon, a special fanfare is heard, telling them that they scored a bonus. If a special shot is made on this court, then only the base value is received.

In volleyball, each camp is divided into 9 parts, and the player must activate the adverse platforms by shooting the ball on them. If he or she aligns three ones (diagonal alignments do not count), following the principle of Tic-tac-toe, the value of the points is immediately doubled, giving the player's team two points. If all of the Bowser Jr. panels are activated, the set is immediately won, disregarding the score. On a side note, items will not appear during a volleyball match at this court.

In Harmony Hustle, Bowser Jr. Blvd. is one of the three courts that are used; the others being Peach's Castle and DK Dock.

 * If a team wins in volleyball by lighting up all the panels, the scoreboard shows a Bowser Jr. icon in place of the team's total score.
