Starfish Hitchhiker?

A recent order of snails brought in MEN, and this guy apparently towards the bottom left:

It looks like a starfish and the arms move like a starfish; snail is in the middle for size reference. Thoughts on an ID? Thanks!

Brittle starfish... Good hitchhiker.

Yeah it looks like that to me too. Just really surprised; it must have been super tiny not to notice and grown a lot in the past 3 weeks.
