Miles's mother, Stella's mother-in-law, and Mitzi's sister-in-law who is often seen doing outlandish things, including dressing up and acting like fictional and historic figures, such as Calamity Jane. She is called "Pookie" by Grandpa Phil and Gertie by Aunt Mitzi. She has a black belt. She and Phil had a similar relationship that Helga and Arnold have when they were Arnold's age (though her pranks were a bit more vicious and extreme), which implies that they are the same age. Miles and Stella Shortman (voiced by Craig Bartlett and Antoinette Stella) are Arnold's parents, Miles being Phil and Gertrude's son. They're adventurous and brave, though Miles appears to be clumsy and tends to end up hurt. They met while exploring in San Lorenzo, where they occasionally crossed paths with the Green-Eyed people, a mysterious indigenous tribe. They returned to the city after Arnold's birth, but were called back for "a final mission" when a friend informed them that the Green Eyes were in trouble; they failed to return, leaving their son under his grandparents' care. Arnold comes across a journal detailing some of their adventures years afterward. His pet pig, Abner, was a wedding gift to his parents from the Green Eyes. In The Jungle Movie, it is revealed that while trying to cure the adults of the Green Eyes who had caught the sleeping sickness they ran out of medicine and began to work on making more, but unfortunately, they ended up contracting sleeping sickness leaving only the Green Eyes' children to watch over them and the other adults. However, they managed to make enough of the cure and planned to aerosolize it so it could cure everyone using the Green Eyes' technology which was activated by the Corazon, a literal heart made of solid gold which was sought by the villainous river pirate Lasombra who pretends to be Miles and Stella's friend Eduardo to trick Arnold in leading him to the Corazon. However, the Corazon falls down a ravine while Arnold, Helga, Gerald, and the real Eduardo are struggling with Lasombra. Fortunately, Helga gets the idea to use her locket in place of the Corazon which she reveals to Arnold for the first time. It worked and the cure is released during the Green Eyes and Arnold's parents return home with their son. Arnie (voiced by Grant Hoover) is Arnold's maternal cousin, who lives in the countryside and
