A handy macro for targeting them, as you fly about:
/tar Aotona /tar Crazed /tar Dirk /tar Fumbl /tar Griege /tar Grockl /tar High Than /tar Hildan /tar Iceho /tar King Kr /tar King Pi /tar Loqu /tar Old Cry /tar Perob /tar Scarlet Highlord Dai /tar Seething Hat /tar Syrei /tar Terror Sp /tar Tuke
(Some mob names are shortened to keep the macro under the 256-character limit.)
It's advised to use a rare finding addon, such as NPCScan or SilverDragon, when going for the achievement to make things quite easier when flying through the zones.
