He was fine with the projectiles, it only gave him more stuff to throw about, but once the one in the coveralls tried to jump on him, he set the minion on fire. At that point, the minion fire brigade responded, dousing him in water before emptying a fire extinguisher on him, and then finally trying to smother him with a blanket while the minion on fire jumped into a barrel of liquid. Which would have been fine, if it had not been filled with the inevitable motor oil. He watched the antics of the minions trying to put out the oil fire, the minion running around and still on fire, before deciding he was done, rampage succeeded. He pulled the oral flamethrower out of his mouth, and put it on a shelf, before sitting down and working on something, at least until the base fire suppression system went off, dousing everyone in fire suppressant foam. And the alarm minion was still using the megaphone to make siren noises.
