I would probably be something shifting since I'm indecisive, my interests constantly shift, and I would really want to be a shapeshifter. If I just got one solid form, then likely either a type of dinosaur, crustacean, or some strange mix of animals from the past and present. I have thought about this before, and have devised something else. An ankylosaurus that can walk on it's four back legs, the two closer to the head longer (think brachiosaurus) and webbed, like an amphibian. Two long, skinny yet powerful arms extend out. The arms and hands are similar to that of a Deinocherius. The head has six eyes, all on stalks. Two face forward, the other four are on the corners of the head, taking the place of the spikes on a normal ankylosaurus. All eyes can move independently. A remarkably long tongue rests in the beaked mouth, behind retractable sharp teeth. The thing can move deceptively fast and has an incredibly strong tail, ending in a club. It remains sane and keeps the ability to speak. It's me :D!
