Gabbro is a minor character that appears in Super Paper Mario.
Gabbro is a Cragnon that was one of many Cragnons captured and bought to Floro Caverns. However, unlike the majority of them, Gabbro did not get brainwashed. Gabbro is found in a room with one of the Pixl, Dottie. Gabbro became good friends with Dottie and was torn at the fact that Dottie had to leave due to her duty to help the heroes. Fortunately, mentioning Flint Cragley gives Gabbro the push to leave since he is a huge fan of Flint. Dottie uses her powers to shrink Gabbro and Gabbro escapes through a small door.
