Money is the Root of All Evil

''The bloons are planning on stealing our money. Save us, and that greedy buddy will help you too... or not."

 is a special mission where you start with a free 0/0 Greedy Monkey you can place where you want.

You have to beat rounds 1 to 65, with a mechanic: when bloons reach the end of the track, they take away your money instad of your lives. You have no lives in this mission, and if you lose all your money, you die.

The reward for this mission is 50 Monkey Money and a permanent buff to your starting money: now, you always start with 100 additional cash. Starting cash for this mission is 1500.

Normal mode, track is Cash Money.

At the end of round 65, the Greedy Monkey you placed at the start of the mission will jump to the middle of the track, and that's when the boss starts.

The traitor Greedy Monkey stays in the middle of the track, just spawning bloons and stealing 1 cash per second. It has N HP, where N = the amount of money you spent on his upgrades + 1200. Each 1 cash it steals from you will regen 1 of his HP. It ocasionally spawns a random number of RBE, between 20 and 100, of bloons. However, for each 1 RBE it spawns of bloons, it'll lose 1 HP. The cooldown between those bloon spawns varies depending on his HP:

3000+ HP: 10 seconds.

Each -20 HP: -1% cooldown.

Minimum cooldown is 1 second.

Also, each HP you take off him will give you back $1.

When he loses all his HP, he gives up, because apparently he lost all his money, and walks alway to who knows where, and when he leaves the screen, the mission ends, and you win.
