This is insipired by the Wizard lord special mission.
The Spike Production Plant is a 4/4 version of a spike factory, but even more powerful. It can produce spiked mines that are extra deadly to ceramic and MOAB class bloons, and can launch an even thicker layer of spike ball storms onto the track. However, all the spiked mines needed to be heated up individually, so each 6 rounds, the spike production plant will consume a tower with a "firey" upgrade, like Monkey Apprentice with the Fireball upgrade, or the Red Hot Rangs of the boomerang monkey. It can also consume other smaller spike factories with White Hot Spikes upgrade.
