Actually, I have just purchased these forms because I have needed for Zombie Cake-Pops. The shape is stable and the design really succeeded (you can tell it's anatomically represented largely correct), only the removal of the Cake-Pops and ice have been more than inconvenient. Since the molds above have a slightly narrower margin, you need more time and a little more skill than normal forms, but the idea is very unusual in itself, and the result of the ice can really be seen!
