Captain Nibs

I got one as a treasure map reward, after completing my expeditions for the week. Haven't tested him yet, but he got a few abilities that are strong against both critters and humanoids.

Great pet. Got from heroic island expidition. I've received two of these, but gave one to the wife. I consider him my undead iron starlette. One of the better undead pets and underrated as of today.

This pet is the answer to undead vs critter. He could probably kill a rabbit under the right circumstances. Rabbits love to kill undead using dodge, burrow, and sratch/flurry. The problem is speed. You would need to pair him with a fox or someone that could dazzling dance in order to out speed the rabbit.

Got this guy last night on normal island expedition. Pretty sure one of the pirate ship bosses it what put this on my loot table for the run. The invasion rares seem to have better drop rates than other rares.

I got him from a regular Island Expedition. I just think like the others, he's a random reward at the end.

 I'm looking up all these new Island Expedition pets on wowhead, and no one is saying much about where they come from.   For the Bloodstone Tunneler, one guy wrote (on Wowhead) that it was "rewarded from" a normal difficulty expedition.  A comment on this site said much the same thing, so I guess you get it in the bag of loot at the end.   Wowhead does call them "drops", but I suppose that could refer to the loot bag.  

I’ve run a great deal of island Expeditions and I haven’t seen this drop. None of my friends have it nor guild mates. Has anyone? Feeling like his bones gave up the ghost
