Gabbro
Gabbro is a Cragnon living in The Land of Cragnons during Super Paper Mario. He is a big fan of Flint Cragley and is one of the few Cragnons to not get caught by the Floro Sapiens amd get brainwashed and turned into a slave of King Croacus.
Gabbro was caught in Floro Caverns, however with the help of Dottie the Pixl, Gabbro was able to hide from the Floro Sapeins. When the three heroes (Mario, Peach and Bowser) arrived Gabbro thought they were Floro Sapeins until Dottie corrected him.
Dottie wanted to join Mario's team but Gabbro didn't want to loose his friend who helped him escape. Dottie said that he could only be with the people who knew how to control the powers of Pixls. Dottie shrank Gabbro so he could escape the Floro Caverns without getting seen.
Gabbro went through a small door and returned back to Downtown of Crag. Gabbro doesn't have any actual important apperance in the game.
