A creature of the pig family, known as a grounger, existed on the planet Endor. In an effort to teach the young Ewoks the proper method for capturing a grounger, Chirpa leaped upon one, subdued it in a wrestling match, and then secured its legs using a rope.
The episode "A Warrior and a Lurdo" of the Ewoks television show featured a grounger; the original air date for this episode was October 25, 1986.
