You can catch the goanna in trees or on the ground. When they're in trees you throw a stick at them. If they're in the ground you might have to dig it out of the ground. If you want to cook the Goanna throw it on to burning flames to singe the skin. Cook them in ashes (put them over the ashes). If it is pregnant lay it on its belly so the eggs do not burst.
