Defeat this guy to access the Stolen Treats and free Metzen the Reindeer to complete the quest You're a Mean One....

If there are enough players around (CRZ actually being beneficial for once), then you don't even really need a tank in order to kill the yeti.

Anyway, casters will need to move around every so often in order to clear the Shrink Heart debuff. If you are melee, watch out for his Cleave. His knockback does the largest amount of damage, but he doesn't use it often. Hunter pets are capable of tanking him - despite Blizzard's general nerf to their pets - but will probably need to use at least one CD to mitigate damage.

If you are below level 89, don't even bother attacking him unless it appears that even your DPS is needed. If you are a healer, then be nice and toss a couple heals around.

Players do not need to tag the greench in order to receive credit for the quest.
