Since it is currently the best month of all time, I declare it Kill a Kobald month! It's rather simple really. Capture a kobold if possible and hold it prisoner until you deem it fit to kill it in the most amusing way possible. Endless possibilities! What about the Giant desert scorpion you found, and its just sitting doing nothing? Well, heres an excuse to chuck it in a pit with a mutant dog-thingy that deserves to perish before the might of the Dwarven Warmachine!
Magma, always a favorite. If possible, dig a pit from the surface all the way into the magma sea and drop him in there for a barrel of laughs.
Then there is of course pitting it against your fresh recruits (be sure to remove all armor and weapons from it!) and let them use their training swords to beat the fellow to a bloody pulp. Oh such fun!
The person who comes up with the most inventive Kobold kill wins a free box of cookies. And remember the Dwarven Warmachine is lording over you. Do NOT fail.
(Elves are not allowed to join. If an elf is spotted near any festive dwarven grounds it is to be shot, hacked apart, stabbed or beaten to death. No exceptions, except to elven kings. All other races besides dwarves must bring beer to partipate in festivities. Kobolds must be captured or killed.)
