The Big One



This is the final upgrade of the path 1 for the Mortar Tower. It costs $8500 (Easy), $10000 (Med), $10800 (Hard). It makes devastatingly large explosions, each popping through 5 layers of bloon. You unlock this at Rank 37.

Trivia

 * These are useful for making the game lag less because of how large the explosions are, the huge range along with the fact that they take out more bloons instantly.
 * The explosion is so big and strong that not even black bloons or zebra bloons can escape; their anti-bomb shells cannot withstand such power.
 * If you set the aim for a Mortar Tower with The Big One on the center of Mt. Magma, it will cover the entire circular center, and its popping mania.
 * This is the only upgrade to increase the popping power of Mortars. Every other Mortar has a popping power of 40, while The Big One has a popping power of 100 (in addition to popping 5 layers, meaning the Big One can pop up to 3,300 bloons in a single shot (if it hits 100 Ceramics with 1 HP left)
 * The monkey next to the Big One is wearing the same clothes as a Glue Hose.
 * This is useful if you face Pink Bloons because it's strong enough to the point where pink bloons wil be instantly destroyed the second the mortar hits them.
 * The Big One is made out of partly Bloontonium because of the radioactive sign on the mortar and the cannon.
 * These are therefore made in Bloontonium Lab.
 * According to the upgrade picture, The Big One cannot safely be touched by the monkeys (even with gloves) without the help of tongs to insert the morter. However the monkey is not using them in-game, so the upgrade picture could be purely for emphasis to show how dangerous The Big One is to bloons.
 * If a lot of these are targeting the same area, they cause some serious bloon damage for everything up to Ceramic Bloons.
 * The explosion sizes are the same of the missiles fired by a Temple of the Monkey GodThe_Big_One's_Blast_Look.png.
 * Bloon Impact and The Big One can pop black+ zebra bloons.
