You don't need any of that! That exactly what I was worried about when I was shopping around. Pop it out of the box and it's basically ready. I think if you have a mature three year old it should be fine. I think it's kind of durable I just don't know if they would appreciate all the cool feature at that age. I got mines for a 6 and 8 year old. I think it said 4+ on the box.
