Pets Versus Pests

So I like using pets ANYONE can find easily and level easily so this is what I used.

Carrotus Maximus: Any frog with Frog Kiss followed by cleansing rain when frog form is active *repeatedly* (third shot should be water jet just in case cleansing rain hasn't had time for cooldown, water jet has a boost against this guy too). Do this till he dies before swapping.

In second position any Strider or Dancing Water Skimmer with Pump and Cleansing Rain, same concept pump cleansing rain, pump cleansing rain, etc.

I didn't need my third pet but I used Emperor Crab with Whirlpool, Renewing Mist, and Surge. All strong against this guy and easy pets to get and worked great!

Gnawface: Start with any fox with Howl and Dazzling Dance, cast Dazzling Dance, you may have time for one cast of Bite but if your health is below 500 jump right to Howl (make sure howl is cast right before death!). Cast Howl and fox should die next hit.

In second position I used Kun-Lai-Runt, cast Rampage. That should be the end of the fight. Third pet doesn't matter.

Gorefu: Use any moth, or three of them. Defeated this guy with, not even kidding, 1 Oasis Moth and he still had half his health when the battle was over. Start with Moth Dust, followed by Cocoon Strike, then while those cool down hit with Alpha Strike. Repeat. Easy as pie.

As of Live:
To unlock this quest, you must be lvl 100, as well as have your garrison upgraded to lvl 3. Hope this helps.

Forget everything and just use Pandaren Water Spirit and Chrominius (and a third pet can be whatever)

1. Pandaren Water Spirit : Geyser -> Whirlpool -> Swap pet
2. Chrominius : Howl -> Surge of Power
3. Whatever is left of your oponnent, do it.

Worked on every enemy. Only had to heal my pets once.
