PEACH: Bowser's Little Helper
Tubba Blubba is the third servant of Bowser to guard a Star Spirit. He is a big blue monster that is half Koopa, half frog, and half kangaroo. He is known as "invinceble" to the Boos because he ate too much Boos and he was never beaten. He was shown in Paper Mario. He was first shown in Gusty Gulch getting ready to eat a Boo named Stanly.
