Green Coin

Green Coins are a new variety of Coins that first appeared in New Super Mario Bros. U. They act much like Red Coins, but these coins disappear much faster and only five groups of three are collected. They always appear in groups of three together forming a clover shape. They rotate in the air but the effect they have is the same as that of Red Coins, as collecting them all gives the player a Power Up or 1-Up Mushroom. They are activated by moving through a Green Ring.

New Super Mario Bros. U
The Green Coins make their debut in New Super Mario Bros. U. If five are collected successfully after activating a Green Ring, the player is awarded a Power Up or 1-Up Mushroom.
