Super easy to beat with a S/S bunny of any variety. It’s a bit scripted and so the moves you need to make (to make the fight very easy indeed) are pretty static.
Bring out your bunny, Flurry>Dodge>Flurry>Stampede (lasts 3 rounds)>Dodge>Flurry>Stampede. Bring out second bunny, Flurry>Dodge. Watch the video for detailed strategy!
The typical Howl/Bomb (Undead Val’kyr/Pandaren Water Spirit/Chrominius) strat works here as well. I just think cute and teeny bunnies are way more fun!
