Would I rather have the ability to fly or breathe underwater? Breathing underwater is cool because I would never drown. There are probably some interesting fish and plant life down there. I could hang out with dolphins and maybe find Nemo. Flying is cool because I could skip over a lot of traffic. I could save kittens from trees. I could fly away if someone was being rude to me. Cons of breathing underwater is that I'm terrified of what lies in the ocean. The fact that most of it is unexplored scares me. Who knows what is down there? Cons to flying, you can get hit by birds or planes but honestly I would pick flying since I would utilize it probably everyday compared to breathing underwater. Side note, have you ever seen a lobster this big?
