Gold Bullet Bill

Gold Bullet Bills, also known as Golden Bullet Bills , are golden version of Bullet Bills that first appear in Super Mario Sunshine.

Super Mario Sunshine
In Super Mario Sunshine, Golden Bullet Bills are only found during the second episode of Pinna Park, where they are fired out of the cannon headed by the Monty Mole. Spraying them with F.L.U.D.D. makes the Golden Bullet Bill explode into coins.

New Super Mario Bros. 2
Gold Bullet Bills later appear in New Super Mario Bros. 2 whenever the player touches a Gold Ring. They behave exactly like normal Bullet Bills, except that they leave a trail of golden Coins behind.

Mario Party: Star Rush
Gold Bullet Bills reappear in Mario Party: Star Rush. They appear exclusively in World 3-2 and World 3-3, where they shoot out of marked cannons decided by a roulette at the start of every turn. The coin trail they leave behind lasts for only one turn. Any player who gets in their way is chased by it until the character finds a space spot.
