Aldo is an adult male bearded goat with brown patches of fur, who is slightly on the overweight side. He has buck teeth and his left horn is fractured. He speaks with a slight lisp. He has tattoos on both arms.
According to the model sheets, he is 5 1/2 ft tall.
He wears an orange jumpsuit and sneakers and a deep purple bandanna on his left wrist symbolizing his gang alliance.
Todd is solicited by two gangs while in prison: the Aryans and the Latin Kings. He is torn between which gang to join, as the two gangs ask him to consider, and make a decision at the upcoming prison mixer.
Todd calls BoJack multiple times, for both advice on his situation and to possibly get bail altogether, but is either ignored or dismissed.
The Hollywood 'D' is then en route to being returned from Mr. Peanutbutter's house to its original location, when one of Mr. Peanutbutter's celebratory fireworks downs the helicopter.
It crashes into the prison Todd is being kept at, where he is moments away from being curb-stomped by both gangs after they found out that he was trying to please both at once. He is saved by the ensuing jailbreak.
He escapes from the prison, at the end of the episode when a helicopter crashed into the side of the building.
- Aldo's name is only known from his model sheet, as it was never mentioned in the episode.
