What is my Pom Pom crab carrying!?

[JoJosReef]

My pom pom arrived sadly with no pom poms and has been living for about 8 months in my tank playing it safe--I have a pom pom crab with pom poms in my other tank, and that little guy is ferocious.

Today, I saw him carrying something, and I couldn't quite make out what he's got. Anyone know of things other than the typical white anemones you see them with that they might decide to pick up and carry?

I tried to take a video to see if this makes it clearer, but I also caught the green porcelain crab attacking the poor pom pom crab.

I put two pom pom's in my 45gal cube and my smaller guy molted and lost his pom pom's. Next day I see him with one pom pom and the bigger pom pom also only had one pom pom instead of two... ROBBED!

Super neat creatures. I have found that they usually lose the pom poms after time. Only crab I put in my tanks lol.
