Moneybags

Moneybags (originally spelled Money Bags and also known in singular as Moneybag ) are enemies that appear in Super Mario 64 and New Super Mario Bros. They are living money purses that have their zippers undone, with two glowing yellow eyes inside, and have yellow-orange shoes. Subsequent games in the Super Mario franchise replace Moneybags with Coin Coffers, beginning with Super Mario 3D Land.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64, two Money Bags appear in Snowman's Land. At first, they take the form of a regular, usually noticeably misplaced, coin, but when Mario gets near one, it transforms into a purse-shaped creature that hops around. After four hops, it flattens up and then walks on the ground for a few seconds. Defeating one earns the player five coins. Money Bags return in the remake Super Mario 64 DS with a slight redesign, and they are also featured in the minigames Coincentration and Intense Coincentration.

New Super Mario Bros.
In New Super Mario Bros., Moneybags are found only in World 5-2 and World 6-3. Like in Super Mario 64, a Moneybags appears as an out-of-place coin at first, before showing its true appearance when Mario approaches. In order to defeat one, the player must hit it with six fireballs, stomp it three times, or use either a Mega Mushroom or a Koopa Shell. For the first two methods, it gives one coin for each hit, and a 1-Up Mushroom upon the last, at which point it is defeated. Moneybags usually appear in areas with several pits, making it harder to chase the creatures by these means. The minigame Coincentration returns in this game, featuring more 3D-esque graphics, with the Moneybags filling the same role.
