Something growing in my xenia

[ScubaSteeve]

Anyone ever seen anything like this before? Found this growing inside a xenia plug. Its kind of rubbery, I noticed it a month ago when cleaning and the xenia closed up I pulled it out and squeezed it and it popped. I thought it was gone but noticed its back and bigger.
