A boss from the Paper Mario (Series) series, appearing in the chapter 3 of Paper Mario 64. It is the sentient Heart (Organ) of Tubba Blubba that was removed by Bowser, making Tubba Blubba invincible. The heart controls the body as if he were a Puppet. Mario must attack the heart to damage Tubba Blubba, where it eventually rejoins with his body, physically weakening him.
