Bowser Jr. Playroom

The Bowser Jr. Playroom is a baseball field in Mario Super Sluggers and is located inside Bowser Jr.'s room. This stadium initially serves as a cover-up for Bowser Castle, into which the stadium transforms after a certain point in the story and whenever the player switches to nighttime mode.

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 (which can break when hit) sitting on them. A giant Bowser Jr. statue also hangs over the middle of the wall and the whole field is surrounded in a train track and building blocks. In the outfield, there are many floor images of Chain Chomps and Bullet Bills. A Chain Chomp or Bullet Bill will pop up if its image was hit by the ball. The Chain Chomps and Bullet Bills will chase the player; the Chain Chomps run on the ground and the Bullet Bills fly. No matter what hit the player, they are stunned and drop or miss the ball. However, the enemies can be avoided if the player runs away fast enough.

The minigame played here is "Graffiti Runner".
