I know dragons are mythical creatures with scales and fire breathing ability, but wouldn't it be wonderful to own one?
It would. What different kinds of dragons are there?
They have legs and resemble a lizard, but I'm not sure how many types there are.
Do they have different colourings?
I think most are green, but I have seen some brown as well in books.
Do you know any names?
Yes, have you heard of Puff the Magic Dragon?  There was a song about him.
No I haven't, how does the song go?
