The CSIRO has promised to step up its dragon research program, after a seven-year-old girl wrote asking them to make her a dragon.

Sophie Lester, from Queensland, sent a letter to Australia's national science agency before Christmas to ask for a dragon, which she would name Toothless if a girl and Stuart if a boy.

"Would it be possible if you can make a dragon for me. I would like it if you could but if you can’t that's fine," Sophie wrote.

Sophie explained in her letter that she would play with it every weekend.
