The Squirky battles vary slightly, I found the ones with Bubble a bit tougher/longer fight than the ones with For Adventure! just because they can avoid so many attacks. 

B/B breed only.  I spotted poor through uncommon versions, using a stone is wise.

Pulled 2 mobs into the water to clear an edge (I was alone) and then a few more to reach the 3 squirkys at the campfire on the lowest level of the island.  The squirkys respawn rather quickly, the first one I'd fought respawned by the time I was done battling the second one.  The mobs didn't start their respawn until I'd battled all three squirkys.

Anyone ilvl 890+ should be ok.

Just ran a 25 and a 25H and had 0 pet drops.  So definitely no 100% drop on any of these.  Grats on the great luck though!
