Puppy + Starfish = Love

I have this starfish on a pile of extra fabric on a bookshelf in my dining area and Rocky can not get enough. Its been an issue. He is in love with this starfish. He jumps up when we are not looking and hides it. I really like where I had it, so I was determined to train him not to take it. Its not working. I must move the starfish to a higher place. Its like it's his baby, he protects it under all circumstances. It cracks us up.
