Bizarre Egg/Parasite. Identify!

[John.Thompson]

I was cleaning the tank and come across and bizarre creature/egg on the inside crevices of my powerhead. Looking for some identification and guidance. Cleaned them out with hot water, frag dip, and some scrubbing.

Tank Critters: I have blue leg hermits, emerald crabs, turbo snails, tiger sea cucumber, sand sifting sea star, White Ribbon Eel.

None of which have eggs similar to that(as far as I could tell)
