MochiCoins used to be a form of currency used by MochiGames and Ninja Kiwi that you could purchase with real-world money or you earn by completing offers. They were used to buy premium content. They had been used in Bloons TD 4, Bloons TD 4 Expansion, and Bloons 2. Purchasing MochiCoins is no longer possible as they have been discontinued as of October 5th, 2012. MochiCoins have been discontinued as of October 15th 2012, but can be traded in for NK Coins anytime for the rate of 80 MochiCoins to File:CoinsIcon.png1 (though sometimes, you can get more than that rate).
