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. At Nighttime, the field turns into Bowser Castle.

The layout is the same as the Bowser Castle stadium of Mario Superstar Baseball. The walls of the field are very high, which makes it difficult to get Home-Runs, and they have toys like Thwomps sitting on them. A giant Bowser Jr. statue also hangs over the middle of the wall. In the outfield, there are many markings on the floor of Chain Chomps and Bullet Bills. If the ball lands on a mark, either a Chain Chomp or Bullet Bill will pop up, depending on which enemy was on the hit mark. The Chain Chomps will chase the player as they go for the ball, and they Bullet Bills will, like the Chain Chomps, go after the player, except in the air. Either way hit, the player will be stunned and drop or miss the ball. However, the enemies can be avoided if the player runs away fast enough. The field is colorful and has many toys for Bowser Jr. to play with.
