Start on the pink blob on the corner, and work your way up and left. A tad licheny, and you're still doing real climbing all the way near the top, so do bother to drag some pads under you.
One of the 20+ great climbs on the Mystery Machine boulder <v4.

All the way on the right on the face that holds Mystery Machine, on the Mystery Machine boulder.

2 pads if you plan on falling from up there.
