Tubba Blubba's Castle is a very large castle that appears in Paper Mario. It is home to the (formerly) invincible Tubba Blubba. This level also contains many enemies called Clubbas.



The outside of Tubba Blubba's Castle is very large in size. It has a very large door that is even bigger than Tubba Blubba himself.


The inside of Tubba Blubba's Castle appears to be in very bad shape as everything seems to be cracked. Tubba Blubba's Castle has many rooms which includes:

  • Foyer: The first room in Tubba Blubba's Castle. There is many enemies in this room called Sentinels that will pick up Mario and carry him out the castle. Mario must use Bow to hide from them when they get close.
  • Hallways: There are many hallways in Tubba Blubba's Castle that usually lead to many other rooms. At one point, Tubba Blubba appears in the hallway and Mario must use Bow's ability to hide from him. Mario must also stay alert of the Sentinels that patrol certain hallways.
  • Basement: The basement is located directly below the Castle. Mario heads down there to get the key in order to proceed further into the castle. There is also a Boo hiding down there telling Mario that he is hiding from Tubba Blubba. He also tells Mario that the secret to Tubba Blubba's weakness is somewhere in his room.
  • Tubba Blubba's Room: This is where Tubba Blubba sleeps. This room has very large objects including a bed. Mario comes here to get the Key which opens the Windy Mill and leads to Tubba Blubba's Heart; the secret of Tubba Blubba's weakness.
