Brytta's Comments

These guys have really odd behavior when you're looking for one of them. I saw multiple 'beast' snowshoe rabbits which would occasionally disappear, and one battle rabbit but it burrowed or fled before I could nab it and didn't reappear in 10 minutes (I assume someone else got it).  Going over to the Dalaran Crater and battling rats is a less exciting but more reliable (and less camped!) way of getting one, ime.  Rabbits popped up as a second roughly a quarter of the time.

Caught one this morning. The rain started at 7:15 am server. I was on a genocide out of frustration, because it was pouring rain on the mainland and a lovely clear red sunrise on the Isle yet again.  It started raining right as I AOE killed both a bonobo ape mob and a battle-able crab, and I was roughly halfway around the island in my scorched earth campaign.  Confirmation biases abound!  Good luck with yours.

I arrived a little after 5 with no active spawns.  Killed everything, waited for repops and nothing.  alt tabbed to look things up, etc, and when I made one last circle around at 5:34 or something, there was one lonely spawn.  Repop/spawns do seem to be based on time and not killing other creatures, looking over your shoulder at the full moon, etc.

I was unable to find this crab wandering the world ready to battle, as seems to be confirmed by wowhead.  He turned up roughly once every 5 battles when I fought rapana whelks in the Briny Muck, though. Insolent crabs, indeed.

{update} as of 5.1 this is no longer true. This pet can be found as a first in the Briny Muck alongside the whelks. Happy hunting!

Found mine directly west, maybe 60 yards from Humboldt Conflagration, when I battled a yellow-bellied marmot (3rd pet was also a gryph).

These show up frequently as a second or third pet in any battle near Writhingwood in Dread Wastes.  However, you will want to head over to The Briny Muck to battle one as a first, because from what I've seen, you can only catch an Emperor Crab as a second in a battle with the whelks.
