What is "goliad"

"Goliad" is the tenth episode of the fourth season of the American animated television series Adventure Time. The episode was written and storyboarded by Tom Herpich and Skyler Page, from a story by Patrick McHale, Kent Osborne, and Pendleton Ward. It originally aired on Cartoon Network on June 4, 2012. The episode guest stars Graham Linehan's children, Wendy and Henry.

The series follows the adventures of Finn (voiced by Jeremy Shada), a human boy, and his best friend and adoptive brother Jake (voiced by John DiMaggio), a dog with magical powers to change shape and grow and shrink at will. In this episode, Princess Bubblegum (voiced by Hynden Walch) begins to fear for her mortality, and creates an eternal sphinx named Goliad to be her successor. Things go awry, however, when the sphinx turns against Bubblegum.

Linehan's children, Wendy and Henry, were brought on to voice Goliad and Stormo, respectively, after Ward saw video of them impersonating Adventure Time characters. Linehan is currently putting together a story for a sequel episode. The episode received largely positive critical reviews, and was later nominated for an Annie Award for "Storyboarding in an Animated Television/Broadcast Production" at the 2013 award ceremony, although the episode did not win.
