What is this eyeball looking thing on this urchin?

That’s a hell of an upgrade on a urchin lol.

Looks like a zoa polyp is taking a ride with the urchin. My tuxedo urchin always has something along the ride. I clean him up once and a blue so he’s able to continue to chomp around lol

If you paint a racing strip on the urchin, it will have the urge to upgrade to dual exhausts.
