Bowser Jr. Playroom

The Bowser Jr. Playroom (Also known simply as Bowser Jr.'s Room in other regions) is a field in Mario Super Sluggers.

The layout is the same as the Bowser Castle stadium of Mario Superstar Baseball. Once again, there are some Thwomps on the sides, that will try to block the ball, making it more challenging to get a Home-Run. In the outfield there are large symbols of either a Chain Chomp or a Bullet Bill. If the ball lands on the symbols, the enemy the symbol is of comes to life and charges in the outfield.

The field is colorful and has many toys for Bowser Jr. to play with. At nighttime, the field turns into Bowser Castle.
