ABOUT THIS CACHE

FIRE MAN
Waste Disposal Robot
Built to handle incineration at the world's largest waste management facilities, Fire Man wields flames that can exceed 7000 to 8000 degrees using his Fire Storm, which not only launches a blast of fire burning bright, but also protects Fire Man himself with a spinning flame shield. But this hot-blooded guy isn't all just blaze and brimstone; at the end of the day when work is done, he likes nothing better than to curl up before the hearth with his pet salamander and enjoy a good book - particularly classics republished in the same year as the then-just-released Kindle Fire; although these days he prefers a good 2018 paperback edition instead. Indeed, his fascination with the ideals of justice would have him chasing Dr. Wily's trail like a mechanical hound - if, of course, Wily hadn't reprogrammed him first. Unfortunately, that's exactly what Wily did, and now all those heroic ideals pass through Fire Man's twisted metal mind like sand through a sieve. Originally, to burn was simply Fire Man's job - but now with Wily's "help"? It has become a pleasure.
Assume North 40 and West 74.
