Luring Bot

I was wondering if anybody had a tutorial on how to skull a gdk bot at easts or even lvl 38, I've been trying for hours now and it hasn't been working, things I've tried:
Drop bone and stand on top of it
Drop bone and have snail move on top of the bone

No luck, Would be well appreciated if somebody can supply a method
