A decent warm up in the area, though there are much better routes nearby (see Wonderful World) at a similar grade. Not the destination route for the Egg by any means, but certainly worthy of a climb while in the area.
The route begins with an out-of-character (though oddly common at The Egg) tough and overhanging start, that may be the crux of the climb. Climb up and past a tufa and into a corner, to a large ledge through a couple awkward moves. Wide stemming gets you to the anchors - careful of the large, loose block near the top. Its tempting to use, but not much more difficult to avoid it completely.
If coming from the Wonderful World, move right along the wall towards the North Face to the next obvious left facing corner. This is Sha Bi Ab Bi. You'll see the blank looking Mr. Greenwood (12b) to its left.
Bolts to a 2 bolt fixed chain anchor. Easy to top rope.
