Echo in the Cave Pet.

I got really lucky tonight I got the Echo in the Cave pet to drop while doing the Elemental event ..was quite surprised it listed as a World Drop too as far as I can find out so far....

Congratulations!
What enemy did you get it from?

Congratulations! It's still unclear how rare it is, exactly how it drops... Every bit of data is good. Enjoy your new friend!

Well, it seems those are not so rare after all. I have got one Echo from the first big air elemental I have killed today - and bought the other three on the auction.
