Here's My idea.
Shadow Monkey
Cash (Buy): 1,200
3-3 : Rounded About well umm Almost a TOTMG on medium
4-4 : 20,000 x 10
This monkey will use it's sneaky skills to slash bloons and pop them.
Right Path :
1. Camo Spotter
Allows the shadow monkey to see Camo Bloons.
1,100 Cash
2. Quick Slashes
Attacks twice as fast,and pops 3 bloons at once.
3,000 Cash?
3. Triple Slash
Attacks three different bloons at once without stopping. (Nerf would be needed)
50,400 Cash
4, Quadruple Infinity Slashes
Will attack 4 bloons at once. Will also instapop Moabs into red bloons.
100,000 Cash
Left Path :
1.Quick Reactions
After popping a bloon,the shadow monkey would move to another bloon at a quarter of a minute.
1,900 Cash
2. Clones
Shadow Monkey will clone itself and will be able to attack bloons in different areas rather than in it's range.
6,900 Cash
3. Triple Cloner
Will Multiply by three the clones that show up (2-0 is 3 Clones,so that means 9 clones at once.)
9,570 Cash
4, Clone Master
ABILITY : Clone Storm. Will make the screen be covered with 2-0 Shadow Monkeys,anahilating anithing.
As you thought, One Hundred Thousand Cash.
