Moneybag Bloon

Moneybag Bloons are the children of Wealthy Bloon, and the parent of two Yellow Bloons. They take 10 hits to pop, no trouble... WRONG! These guys hve a shield that is resistant to everything except your clicking, and with all those other bloons on screen, try clicking it, as the clicks do not go through other bloons. The shield takes 5 clicks, and after that it will go to your life bar like Butler Bloon does with your money, and slowly leech them away(1 life evry 2 seconds). To get them off you have to click them 3 times each. After all of that trouble you can finally pop them.

Appearance
It is a bloon wearing a cloth sack with a Mario(You know, the game series) coin from Super Mario Galaxy on it. It alternates speeds to match the bloon layering over it(which can be a pain during the shield part) and takes away 5 lives when getting through.
