Careful With That Needle!

Careful With That Needle! is a premium upgrade that can be purchased for 30 Ninja Kiwi coins. You can turn it on and off in the premium store. When it is on, you can right-click on the game to turn your mouse pointer into a needle. Then you can click on bloons to pop one layer per click. However, each click costs $1. The needle is unable to damage lead bloons, but can be used to break open a ceramic bloon (though this takes multiple clicks). The needle is only able to do 1/2 of 1 damage to MOAB-class bloons. When you want to stop using the needle, you must left-click. Otherwise, if you click on one of your towers while you have the needle out, it will do 1 damage to the tower (but will not charge you any money to do so).
