I've now gotten two of them. First one I got the first day it was implemented while doing the fishing skill quest off the pier on my shaman. I wasn't even aware there was a pet at the time. Second one I got November 2, 2014 again doing the same fishing skill quest off the pier on my paladin. So you don't need to be near the cave with the ?? mobs. This drops just fine off the pier where you fish for the fishing skill quest.
