Cactus monkey

A cactus monkey looks like a green monkey with spikes all over it (What would you expect?). It pricks bloons 3x as fast as a dart monkey, but only has a range as far as an unupgraded ice monkey, and does not peirce any bloons. in short...

Range: ice monkey

Apperance: green with spikes.

Atk speed: 3x speed of dart.

Peirce: none.

cost: 900

Eye treatment (500)
Spikes are pulled out of the monkeys eye, increasing his range to 1/2 of a dart monkey.

Pointy spikes (1000)
Shoots 2x as fast.

Ripping spikes (2500)
The spikes rip through bloons, deflating them. After being hit, they pop 1 layer each 5 seconds. (1 HP for bloons with HP)

PUNCH! (6000)
The monkey now gets 2 atacks: poking a bloons with an atack that atacks 6x speed of dart monkey, as well as ripping them, and punching them, popping 5 layers but only atacking at 1/2 speed of a dart monkey, with ripping.

Spikey fist of fury (12500)
Now, the normal atack deals 2 layers and the punch deals 10 layers! enough to destroy a ceramic bloon in 2 hits!

Carpet of spikes (insert cost of spike factory here times 1.5)
Now, shoots 20 spikes on the ground that act just like road spikes, and replenish at a rate of 5 per second (but there can only be 20 at one time. also, if 3/1, then the spikes will rip, and if 5/1, the spikes will pop 2 layers.)

Bloontonium-injected monkey (1000)
can now pop lead and frozen bloons.

Hurl (3000)
Now has to range circles: the initial one and one 3x as big as a dart monkey. (5x if upgraded to 1/3) Now, the tower can shoot an enormus spike, that has 1000 popping power, pops 3 layers of anything it comes across, and is VERY powerful. But, with great power comes a downside: it can only shoot once per 10 seconds, and after slung, the tower cannot use the basic attack for 1.5 seconds.

Fast hurl (6000)
Can now hurl once per 3 seconds, and the cooldown for normal atack after hurling is shortened to hald a second.

Thorny king (15000)
has 2 1/1 cactus monkeys next to him that cant be upgraded, his thorn has a 1.5 second cooldown, no cooldown for normal atack after thorn is used, and has a skill:

Lord of all thorns: all cactus monkeys on screen (including itself) shoot at 3x speed, spiney things (like the spike factory) shoot at 2x speed, and its raning spikes that deal 1 damage, for 10 seconds. (2 min cooldown)
