Living Caves 2000: The Original Kobold Midnight Massacre! is a collection of three tournament adventures for the Kobolds Ate My Baby! 3rd edition roleplaying game. From the back cover:

Every once in a while an enormous group of people gets together with one goal in mind... to play Kobolds Ate My Baby! (NO ONE was more surprised than us to learn about this!) Unfortunately since the manuscript to Kobolds Ate My Baby! Large Scale Combat and Fondu! was lost during the conversion to 3d edition the proper forum for a such [sic] large number of Kobolds to gather and do battle was never availible [sic]. To save ourselves from the tedious task of writing such a boring book again, we decided that it would be more fun to have large groups of Kobolds compete for the honour of being the Most Deadly!, having the Fullest Belly! and just plain survival. Living Caves 2000! contains all you need (besties from [sic] paper, pens, dice, friends, tables, chairs and a large auditorium. [sic]) to run a Living Caves! Kobolds Ate My Baby! Third Edition tournament! On the off chance that you don't have an army of friends ready to play, it can also be used as a campaign or even single adventures in a standard game of KAMB 3E.

Inside you will find 3 officially sanctioned KAMB 3E Living Caves! adventures, Tournament Rules, advice for Uber-Mayors and conversion rules for using this product with Kobolds generated using the original or "classic" Kobolds Ate My Baby! game.
