Monkey Cloud

The Monkey Cloud is a tower which can be placed everywhere, including lava. It is placed in Air, so it will make enough space for your other towers. Just like the Pontoon, you can place monkeys on it, that can still attack the bloons, but have much longer range and +1 popping power. Spike Factories and Tack Shooters will not work. It will also rain sometimes, popping 1 layer off bloons. It is unlocked after beating Weather Mode. Unless upgraded, you cannot place Super Monkeys on it.

Costs $850 on Hard, $650 on Medium and $525 on Easy.

Path 1
Tougher Clouds - Tougher clouds can protect the towers on it from the dangers that lie below. Also can support the weight of a Super Monkey.

Cost: $250

Rainbow Clouds - Some pesky rainbow bloons joined the good. After the rain attack, the Cloud will fire a rainbow with some good area of effect.

Cost: $450

Coolumbus Clouds - Gives you a lot more space to place your towers, and now there are 3 different rainbow attacks!

Cost: 2,500$

Cotton Candy Clouds - This yummy cloud will make the monkeys happier, making them fire 20% faster. Oh yeah, and by the way, did you know prism lights are better than old fashioned rainbows?

Cost: 3,750$

Path 2
Glue Rain - The regular rain will become a glue rain. The glue is the same as the one of a 0/1 Glue Gunner.

Cost: 450$

Acid Rain - Better stay out of this--pops bloon twice, then damages them with corrosive glue. Sometimes, it will not work and still be glue rain though.

Cost: 1,250$

Lightning Stroke - Strokes 1 random bloon out of the range of the placed tower by a powerful lightning that removes four layers off. However, takes 5 seconds to recharge and Ceramic Bloons/M.O.A.B.s are immune to this.

Cost: 3,100$

Cloud Nightmare - Destroys all the towers placed on it, but gains a new tornado attack (4 Tiny Tornadoes), Super Lightings that can hurt M.O.A.B. Class-bloons by 25 damage, and gains a Special Ability: Cloud Night: the whole area will turn grey, then an avalanche of darts will strafe the whole area.

Cost: 16,000$

Glitches

 * In BTDB, when placed at the edge, a part of it will stick out to the enemy's side.

Trivia

 * "Coolumbus" upgrade's name is based on one type of cloud.
 * If you upgrade the tower to 2/2 or 2/1, the glue/ acid will dissapear form the tower's appearence.
