Lt. Gronk was the leader of a team of gorilla mercenaries in the video game Sly 3: Honor Among Thieves. He was hired by Carmelita Fox to help Interpol stop Octavio in Venice. Lt. Gronk and his team appear in Australia to attack Sly as he tried to climb Carmelita to pry the Mask of Dark Earth off. Lt. Gronk and his team later appear at Kaine Island to attack Dr. M's monster. All the members of his team are equipped with missile launchers and jetpacks. Unfortunately, he and his mercenaries all suffer from very bad luck. In the events of the game (as well as in the bonus cartoon Goodbye, My Sweet), they have been beaten up by the Cooper Gang during one of their heists in Switzerland, tricked into fighting a losing battle against Octavio's Vincenetti gang in Venice; a sizable group were caught in the explosion caused by the destruction of the Mask of Dark Earth in the Australian Outback, and they were all either killed or badly injured by Dr. M's giant mutant primate on Kaine Island.
