Humanoid Battler of Kalimdor

[npc=68846] 1/2/1
[npc=161921] 2/2/2
[npc=68659] 1/1/2

This worked for all the battles, I never had to use 3rd pet.

The NPC's for the Family Battler of Kalimdor achievement can be found in the following locations from the north to south:
It doesn't seem that besides going up to level 25 there are any changes to the pets. Zunta still uses two pets which are both common in rarity when engaged with a full level 25 team.

Note:
The battles are daily, this means that to complete the meta you will need to revisit the trainers for a total of 10 days.
And to avoid anything not completing it seem it is best to complete these on a Horde character.

As you might have noticed, as of Patch 12.0.0, you can only challenge the Pet Battles Trainers in Kalimdor, Eastern Kingdoms and Northrend once per day.

Which means that for the new meta achievements being introduced with Midnight's Pre Patch, it will take a minimum of 10 days to complete (one day per pet family).
