Looking at these statistics you'll think that this is imposible. How could A 12 Year old be so tiny? Well I have done some research....Alot of research and these are the results I came up with. Watching DB I did notice that kid Goku is very short but when he turns 18 he is pretty tall. Could this mean that the sayian grouth rate is different? Well theres alot of things about sayians that are different from us humans. We know that they always have black hair. Sayians onley grow hair on their heads they also grow facial hair as seen on vegeta in GT and king vegeta. Kid Goku is a very energetic and sweet boy. He has a very kind and loving nature and pail skin witch was probably passed down from his mother. No one knows who Goku's mother was but Im guessing that she was a kind loving womon. So this basicly sums it up. Knowing me I could probably go on and on about kid Goku but We need room for other stuff.
