This mob is the Shaman type pet of Syrrengar the Hunter (Quest Giver), very large walking boar type model. I pulled a drake and Vakka added. I was two boxing my 63 shaman and two mobs was getting to be too much for the 1800 quick heal so I gated the Shaman then FD'd and waited for aggro to clear. Vakka was still slowed so I decided to take him down. He was very low on DPS when slowed and dropped a pearlescent wolf tooth. So, if you are pulling around this quest NPC be aware that his pet can add.
