tubba's heart
A boss from the Paper Mario series, appearing in the chapter 3 of Paper Mario 64. It is the sentient heart 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.
