From spring about a year ago.

Old description:

1rst out of 2 mystery designs for   RoxCross

This egg's shell iwas smooth and clear. A gooey yolk, visible through the shell, was oozing out of the cracks. It nested in its own goop and spines.This egg hatched into a spiney, toxic critter!

You can find the rest of the eggs here: http://www.furaffinity.net/view/16180145/
(All are taken, but I do custom designs for $15)
