To the side is a picture of me and my pet. You may know a hunter like me who was lucky enough to get the hydra pet, you may also know they have the most annoying idle sound in the world. This 'addon' will fix that problem.
Note: At some point in 2015 the extract location changed to the root WoW folder
Simply extract the rar file to
*World of Warcraft Directory*\
*World of Warcraft Directory*\Data\
or for some people
*World of Warcraft Directory*\Data\enUS\
