Worked First Try for me, and you should even survive some unlucky crits.

Edit: Formatting, consistency, spelling & optimized strat.

did it with 1) Iron Starlette 1-1-1 2) Direbeak Hatchling 1-2-1 and 3) Clockwork Gnome 1-2-1

for the first opponent, wind-up supercharge wind-up, for second wind-up wind-up then powerball untill you die, switch to hatchling - ironskin, swarm, predatory strike, swarm again and you die, bring gnome, build a tower and then use metal fist

Won like this on my First Try

For the first time, we have a pet battle underwater. I was unable to find him before I checked the wowhead video, because I just assumed the WQ marker was off so I rode along the coast and islands.

So to make it clear, the WQ marker is perfect. Just swim down when you reach it.
