I wish I'd taken a screencap, but one time walking down from Perdida I could literally see three separate Tokotokos on the map in my immediate vicinity. I almost wept tears of joy, but my eyes were all dried out from the tears of sadness that grinding brings me.
One easy way to do it is to run in there and look at the run speed of the familiar. If it's really fast, run opposite direction. That way the familiar doesn't disappear, then you can go back in and corner it or w/e it wish.
