The Spike Factory is a tower in Bloons Monkey City. It is available to unlock after the player reaches City Level 5.

It dispenses spike piles onto random areas of track. Spike piles each have 5 pierce, with a visual representation of pierce based on pierce remaining. Spikes last up to 70 seconds or 1 round, whichever comes first. It can be improved to strengthen each spike pile into spiked balls and mines, or attack significantly faster and disperse MOAB-shredding spikes throughout all paths.
