Guild Achievement: Kill a total of 50.000 critters
Tactics: A few tactics of how this can be achieved fast. -There is a tunnel in north-western eastern plaguelands that is full of critters, the respawn time isn't very good though. -The Tundra penguins in Northrend are a good farm place and respawn quick. -In the Worgen start zone there is a tunnel where critters keep respawning, you can easily get thousands of critters an hour, some say 10k/hour.
