While it may seem like super-slow-mo to us, sea stars actually do crawl on the seafloor!  Want to see it for yourself?  Click here to watch this BBC time-lapse footage of sea stars moving.

So HOW exactly is it that they move?  Those orange strands that you see in the picture below are actually feet.  But not any ordinary feet.  They are filled with water that is contained in a system of tubes inside their bodies.

So, they are powered by water, by squeezing it into their tiny tube feet to expand them and move them forward!

Oh, and could sea stars really see the magic pearl and where they were going?  Yes!  Sea stars have eyespots on the ends of their rays (arms) which allow them to detect light and dark and also see very general images fairly close to them.  So, yes, while the pearl may not have been as clear of an image to them as we would see, the sea stars certainly were able to see the magic pearl!
