Officer Unogopaz

Officer Unogopaz is a large tiger-like Moggie who poses as the Kickball Stadium's guard. He makes sure that nothing but Stonies can get in to play kickball. Banjo and Kazooie try to get past, but Unogopaz doesn't let them since the game's tickets were all sold out when they were playing Banjo-Kazooie. Once Banjo is transformed into a Stony, Unogopaz still sees through his disguise, but lets him pass since there's a shortage of players in the kickball game.

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. Banjo himself denies this, but he's not fooled (especially once Kazooie says something).
