Officer Unogopaz

Officer Unogopaz is a large tiger-like Moggie who poses as the Mayan Kickball Stadium's guard. He makes sure that nothing else but Stonies can get in to play kickball. Only once Banjo is transformed into a Stony will Unogopaz allow them to pass (even then, somewhat reluctantly).

Trivia

 * The name "Unogopaz" sounds similar to "You no go past", referencing Unogopaz's job as a guard.
 * Unogopaz is apparently the only character to recognize Banjo while transformed.
