To expand on Charlie's reply -
Notice that the bulk of the material is in the wing/back of the fly, with only the white
under the tube. The tube acts as the keel and the lighter wing rides upright under tension on the swing.
If you look at crazy charlies (the fly not the tier), the bead chain eyes don't look heavy enough to keep the hook up, but with all the material on that side of the shank, it adds enough bulk/buoyancy.
I think the Black Francis white and purple bunny tube could easily run with the hook point up in the bunny wing - avoiding the rocks when swinging deep.
Just a few thoughts...
