Corncornos

Corncornos are a brand of nachos that appear in "Irrational Treasure."

History
Dipper and Mabel Pines are first seen eating them in the opening scene as they are driving through town with Grunkle Stan. Mabel then puts some on her ears as nacho earrings, commenting about how funny she thinks this is, and Stan replies that whether on this is true is debatable. When Mabel goes on stage during the Pioneer Day opening cermonies, Pacifica Northwest makes fun of Mabel for wearing the chips as earrings, as well as Mabel's overall silliness, thereby causing her enemy to be embarrassed and leave the sight with her brother. As the two talk at the statue of Nathaniel Northwest, Mabel talks about how Pacifica is always putting her down and removes her nacho earrings in shame.

Trivia
Corncornos are the first seen eatable food not made by Nyums.
