Gold Banzai Bills are golden counterparts of Banzai Bills and large counterparts of Gold Bullet Bills which first appear in New Super Mario Bros. 2.
In New Super Mario Bros. 2[]
Whenever Mario or Luigi touches a Gold Ring, every Banzai Bill turns into a Gold Banzai Bill. They behave exactly like normal Banzai Bills, the only difference being that they leave behind a two-row trail of coins in their wake. A Gold Banzai Bill can be defeated using most attacks, and grants 20 coins upon being defeated.
