On like any castle, This castle has lots of chambers. (Before making his castle larger, Bowser Jr inform his dad that the only way is to take over not just the Mushroom Kingdom, but a new land call Haylon. To do that they need the power of the Talisman Gems and the Grand one that controls the main 9. Bowser sent his minions the steel the 9 Talisman Gems and the Grand one, but before taking over Haylon Island, they now must make Bowser's Castle Larger.) Bowser and his minions use the Grand Talisman Gem and the other 9 to create a larger version to his likeness, he has use the castles from the previous episodes, and merge them together into one big castle.
