For an alien that looks like a giant, eyeless five-legged spider made of rocks, Rocky in Project Hail Mary is actually rather cute. He has a peppy energy reminiscent of a puppy (not to mention that he is approximately dog-sized), and it's fun to just watch him wonder at all of the new discoveries he encounters during his time with Ryan Gosling's Ryland Grace. But before you start having fantasies and penning any fan fiction, the film's directors want to make something clear: Rocky is definitely not a pet.
