I bought a blue sponge sometime back from Reborn and just today i noticed this thing that was attached to it.
It seemed like some clam to me because it closed when i turned on my main lights but opened afterwards.
There's also a couple of smaller ones on its right. It's like attached to some greyish matter to the sponge, this greyish matter has also glued itself to the LR where i placed it.
Sorry i couldnt get a better picture of it, my cam's pretty lousy at close shots. Thanks!
