I make a small shaft near the top of the wall, just big enough that I can climb up to it and half hang out. I then cut a small hole in the roof to grab onto with the axe.I walk across the roof (Flat or slanted I've done it before to shingle a house so don't fucking say I can't). When I get to the other side A break down one of the walls that leads to the cake.
I have another one too, Cut open the wall right next to the brick one and keep doing it until it is all gone. If I'm right this brick wall is in the middle of a single wall so I can just cup open the other side and get in to eat me cake.
