Mine favor one spot for some time, then switch to another one for a while - maybe two weeks here, one week there, then back again. Or sometimes alternate sporadically between two or three preferred spots.
Status of the plants can make a difference - my Jackson's spent every night on his Hibiscus from the day I got him until the plant stopped blooming, then never wanted anything more to do with it.
Nice Peanut! (and nice Pygs.)
