Andrew's grandmother appears in the Mario Kart 8 From the Pit episode, "Item Techniques". Andrew tells the viewer if they are looking for "Racing 101" to go down the hall, where it is being taught by his grandmother. A clip is then shown of an uncomfortable Andrew riding on the passenger seat in a car being driven by his grandmother as opera music plays at a loud volume.

Andrew's grandmother is seen on a picture along with Andrew and presumably his grandfather in "Get Creative" when Andrew is demonstrating the "Couch-Flip Mirror Trick".
