WOW: Critter Kill Squad Achievement

Kill 50,000 critters Achievment can easily be done by grinding this pack of critters that seem to respawn instantly. Completing this Achievement will unlock the Armadillo Pup Pet.

Go to Eastern Plague Lands and go up Thondroil River into the cave at the end. (Coords: 4.2, 36.1) The cave has literally 100+ critters spawned at the same time with a insane respawn rate.

I found it useful to also eat a Stormchop - Item World of Warcraft for even faster killing.
