W.A.A.R.M.

The W.A.A.R.M. (Weaponized Auto-Attack Rumble Miner) is a semi-blimp that is a copy of the D.R.I.L.L., so it should be deleted! a massive mining machine that pounds at the ground, creating shockwaves in the air that stun all bloons that pass within the range of the tower for half a second, as well as popping them. Cost: $1250 (Attack speed = Ice Monkey)

Path I

 * Harder Strikes: Hits the ground harder, increasing the amount of bloons hit. Cost: $510 (Increases range to this:
 * Core Drill: Adds a high-power, automated mining drill to the W.A.A.R.M. The drill burrows to a random spot in its range every ten seconds, and, when it comes out, it pops five layers off of the bloon directly over it, and does some serious damage to M.O.A.B.-Class Bloons! Cost: $770 (The W.A.A.R.M. cannot attack blimps without this upgrade, and it does 10 extra damage to blimps, along with the 5 layer damage it does to normal bloons.)
 * Gem Extraction: Every minute or so, the W.A.A.R.M. will find gems, which give you some extra cash. Cost: $1250 (Each gem is worth $60, and will only be found during a round.)
 * Advanced Mining: More valuable gems will be found, giving more income! Cost: $6800 (Each gem is now worth $240.)

Path II

 * Dust Cloud: Slamming into the ground now kicks up dust, confusing the bloons for twice as long! Cost: $385
 * Furnace Blast: Give me fuel, give me fire... Cost: $850 (Burns all bloons within the radius of the W.A.A.R.M.)
 * Earth Tremors: The advanced core rumbler now shakes up the ground, scattering bloons backward on the track. Cost: $2500 (Same effects as Downdraft, but only happens every attack.)
 * Earthquake: Earthquake Ability: Starts shaking up the ENTIRE MAP, popping random bloons all over the screen and opening up fissures at random points in the track. The fissures act like Bloon Traps with infinite capacity. After ten seconds, the shaking dies down, and the fissures collapse. But, for the next thirty seconds after the quake, aftershocks will occur, which have the same effects, but occur over a shorter period of time. The first two last for five seconds, then the next two last for three seconds, and the last one only lasts for one second. Cooldown: 125 seconds. Cost: $11,900

Trivia

 * This tower is a reference to the D.W.A.A.R.P. from Kingdom Rush: Frontiers.
 * The BGM switches to the Kingdom Rush boss theme whenever you use the ability. (Sorry, I can't find a link for it... :S)
