Munny (マニー, Manī?) is the currency used throughout the Kingdom Hearts universe. It is used for all purchases in Kingdom Hearts, Kingdom Hearts II, Kingdom Hearts Birth by Sleep, and Kingdom Hearts 3D: Dream Drop Distance, but is replaced with Moogle Points in Kingdom Hearts: Chain of Memories and Heart Points in Kingdom Hearts 358/2 Days. Kingdom Hearts 358/2 Days does include munny, but it is used only as payment for panel synthesis. Its name is an intentional misspelling of "Money", much like how "Honey" is frequently spelled "Hunny" in the games. Munny Orbs come in three sizes, each worth varying amounts of munny. Small orbs are worth one munny, medium are worth five, and large are worth twenty.
Munny is never dropped by bosses, but is dropped by most minor Heartless and Nobodies in Kingdom Hearts, Kingdom Hearts II, and Kingdom Hearts 358/2 Days. Trinity Marks in Kingdom Hearts often contain troves of munny, and Gambler Nobodies can relinquish a jackpot of munny if defeated at their own game. The final method to obtain munny is to sell off unused items to the various shops.
Sora can also drop a lot of his munny by slipping on a Bouncywild's banana peel, although he can pick it back up if he hurries. It is also possible for Heartless to slip on these peels and drop their own munny.
