Are you referring to the mythical creatures of folklore and legend or big lizards?

There are dragons there, great big ones approx 20ft long.
usually on top of a truck in the carnival.

live ones are approx 1 inch to 5 inches.
the small ones are welcome visitors in any of our apartments/rooms as they east any flying insect, eg, mossies.
any over a couple of inches are usually seen in the undergrowth or gardens etc.
