Puff-shroom

The Puff-shroom is a Plants vs. Zombies-themed tower. It costs $70 and pops 1/4 of a layer per shot (4 layers per shot to things that take more than 1 hit normally). It fires at the same rate as a 0-0 Dart Monkey, but with only one-third of the range.

Greater Range
Cost: $95

Description: Boosts the range, improving effectiveness.

This upgrade boosts the range up to 105% of the 0-0 Dart Monkey.

Frequent Firing
Cost: $210

Description: Makes the mushroom more awake, making firing easier.

Fire rate is boosted by 40%.

Smog Blaster
Cost: $620

Description: Spores are deteriorated into a spray of plastic-destroying smog, allowing even more poppage.

Basically, spores are turned to fumes. Fumes have a minor spread, like that of a 2-0 Dartling Gun. Fumes deal damage 2 times a second to bloons and last 1.5 seconds. They also pop through 1/3 of a layer instead of 1/4.

360 Smog
Cost: $2740

Description: 7 more fume tubes are added just to severely increase overall popping.

The description covers most of it; the tower is similar to the Tack Shooter once it gets this upgrade; however, it deals less damage, has more range, and can pop a lot more than 1 bloon at once.

Solid Spores
Cost: $310

Description: Spores are compressed, causing more damage.

Damage is doubled. Stacks well with 360 Smog.

Spore Shockwave
Cost: $90

Description: Sound is compacted in to the spores, allowing them to break frozen bloons.

Basically, this is Sonic Boom.

Spordnance
Cost: $3190

Description: Packing specialized explosives into your spores causes massive poppage.

The spores now explode with the force of a 1-1 Bomb Tower. They pop through TWO layers of bloon, and deal an amazing 32 layers to bloons that have more than 1 health; this is enough to obliterate an entire Ceramic bloon. Black/Zebra bloons are immune to this, but the initial impact of the explosive spore does pop through a layer, if the bloon is what is hit first.

Sporeferno
Cost: $17230

Description: Sporeferno Special Ability: Melt bloons down into tiny heaps of plastic with temperatures unseen on Earth, destroying them entirely. Does 2,000 damage to MOAB-class bloons.

The ability itself is covered, but it doesn't just get that; monkey napalm is included in with the explosives, melting down bloons like Burny Stuff. This allows Black and Zebra bloons to be popped easily. Burning bloons are popped once a second after being hit with a Sporeferno Spore; this lasts 25 seconds.

Trivia

 * This tower is based off of the Puff-shroom from Plants vs. Zombies.
 * "Spordnance" is a pun on the words "Spore", its projectile and how mushrooms make more mushrooms, and the word "Ordnance", a weapon or explosive.
