Oil Slick by Evan Baughfman

Glistening, black goo coated the surface of the penguins’ pool.

Albino birds huddled, squawked on land. Though blind, the gentle giants could sense the presence of something unnatural.

I thrust a cattle prod into the “slick,” zapping the dark mass, startling its many eyes open.

Tentacles formed, flailed.

Ragged mouths cried, “Tekeli-li! Tekeli-li!”

Then, silence.

I radioed other keepers. “Shoggoth escaped its tank again. Stunned it. Bring barrels for transport. Don’t forget the lids.”

Had to discover how the creature was getting loose!

Its jailbreaks were giving the Deep Ones needless confidence and always threw Nctosa and Nctolhu into frenzies.
