Ferbus is a Monotomonax, a furry bipedal bear-like alien with a beak who means no harm to anyone, but he has been known to get people into trouble. He wants nothing more than to be at Dex's side. Ferbus loves over eating until he is sick, his big appetite can get him into some trouble at times, but fortunately, Dex manages to bail him out at the right moment. When Ferbus first arrived, Molly and Albee had to hide him due to Hal's allergies, but Hal is not allergic anymore around Ferbus; once he revealed himself, Ferbus was accepted as part of the family. Ferbus sleeps in a small room underneath the Stewart's stairs.
- The costume for Ferbus was created by Chiodo Bros. Productions.
