Roof Top Glitch - one I can't do

This is one of the glitches I want to learn! Also, the party glitches! (I think I know the Horses Only Party glitch and the Wolves Only Party glitch) If you know these glitches I'd appreciate it a ton if you told me! :) P.S. Please become a member of my blog if you can and/or comment! :) Thank you!!
