Munny (マニー Manī?) is the currency used throughout the Kingdom Hearts series. It is used for all purchases in Kingdom Hearts Union χ, Kingdom Hearts Birth by Sleep, Kingdom Hearts, Kingdom Hearts II, Kingdom Hearts coded, Kingdom Hearts 3D: Dream Drop Distance, and Kingdom Hearts III.
Munny is never dropped by bosses, but is dropped by most minor Heartless in Kingdom Hearts and Kingdom Hearts II. 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.
Roxas and his friends in the Simulated Twilight Town spend the second day earning Munny for a trip to the beach by doing odd jobs. However, once they go to buy the tickets, Riku bumps into Roxas and snatches the Munny Pouch, since the beach had not been programmed into the simulation.
This Munny Pouch filled with Roxas's hard-earned Munny is later given to Sora, although the pouch is treated as a Key Item, and therefore the Munny within the Munny Pouch cannot be spent, or otherwise used for any purpose.
