Urchin ID

I have 3 of these and they all have shells stuck them. What kind of urchin are they and why are there shells on them...

Can’t tell what kind but lots of times urchins will pick up shells or corals or anything they can find and use them as camo and will wear them for a period of time

Probably picked them up while roaming in the tank. They tend to do that alot. Mine does it all the time.

Looks like pincushion to me. They pick up shells for camoflauge.
