MPPM: Tainted Waveling

Ahh, Lady Vashj. Once a beauty to behold, now the wielder of corrosive death. 'Tis a shame she must be vanquished, but that's the way the dog biscuit crumbles, right?

The Tainted Waveling is the prize you're after, though I suspect some of you may have one already. You are, of course, seasoned veterans of Pet Battles. So let's hear your stories of triumph either from your adventures in Serpentshrine Cavern, or the tiny battlefield with your poison-spewing companion!

I should note that you don't actually have to take down Lady Vashj, but she does deserve some righteous smiting for her tainted actions. (See what I did there?)
