Mount Journal
The locals in Halfhill swear that whenever a batch of grain is missing, a farmworking instrument is misplaced, or a bushel of berries can't be found, you can hear a mischievous squeaking, and are reminded to slow down and accept what life gives you.

''It's not quite certain where Squeakers found his incredible wings of jade. Perhaps he outwitted the Jade Serpent herself. Now the world's first flying rat is ready to set out beyond Pandaria and spread mischief across Azeroth.''
