So I randomly caught 7 Rhesus Macaque (sp?) in some cage traps... Wanting to have the cages back, I tamed them and started butchering them.
Unfortunately a Miller, soon to be Wrestler, adopted 3 of the screeching poo flingers. Part of me would dearly love to see my fortress be over run by monkeys, but I'm thinking of modding them, so I can make them War Monkeys.

.
I'm building also large arch, so I could make a bunch of small bridges and station the monkeys on the bridges in the arch. Then when a goblin invader steps on the pressure plate it would retract the bridge directly overhead, and dump a monkey on it. from 5-6 z-levels. probably won't do much more than stun the goblin and the monkey, but that should be enough for my military to rush in and finish the invaders off.
Edit: jst some spelling.
