Coin Coffer

Coin Coffers are enemies that first debut in Super Mario 3D Land. They have smaller eyes on top of their head, are round, have a lighter green color, and slightly looks like a frog's head, as well as a purse. Coin Coffers react similar to the Moneybags as they attempt to run away from the player. In this game, they contain ten coins. Hitting a Coin Coffer in any way causes it to drop a coin, dazing it, and after five hit, it spits out the rest of the coins it contains before it is defeated. Ground Pounding one causes it to spit out all of its coins before being defeated. When hit by Mario under the effects of a Star, its ten coins are dropped in a ring shape. Coin Coffers first appear in World 2-3, though one can be found hidden in a rock in World 2-1.

They also appear in New Super Mario Bros. 2 similar to how they did in Super Mario 3D Land. They can appear after activating a Red Coin Ring too, giving 8 Red Coins.

They are also supposed to appear in New Super Mario Bros. U.
