My last post was quite weaksauce so im gonna try to redeem myself
The quest "tooga's Quest" in thistleshrub valley gives you a cute big ol' turtle that follows you around for 30 minutes and fights and is quite a tank.
He does about 30 damage a hit and he fill follow you along around tanaris
But dont run too far because hes a slowpoke and you will lose him and fail the quest
He's also a source of comic relief if your bored he says things like "i wish you could just pick me up and carry me"
I searched extensively for anything about this. Sorry if my image link doesnt work im new to image links
Edit: Bonus! for casters/ranged he can cause the daze affect!
