Urchin question

[crazzyreefer]

We have had this Urchin for the last few months, today it is carrying a white/clear ball in it's spines, can some one tell me what it is? It looks like eggs, but I thought they are inside an urchin, The ball is vary complex looking, unfortunately I had to scale down the photo resolution so its a bit blurry.

Can't get the pic to open BUT
Urchins are known for collecting items around the tank and sticking them to themselves.
It could be a small sponge they picked up?

cant seem to get the photo to post... it is in my album, I would consider it a plastic X-mas light bulb tip, but its vary soft and moves with the current, so it can't be that.

Yeah I see it now... RC servers were throwing a 500 error before, it's working now..
So blurry it's tough to tell but I still say a sponge.

Weird looking. "The sphere"

I found out it was their Anus from the invert forum... vary cool, the ball looks like a clear geodesic sphere, I had a great clear pic and then it wouldn't load to the server so I had to compromise the quality to get it to load to RC album. As long as I have been in the hobby, I am still learning things....
