I can confirm that MoxCo’s trick works perfectly. You only need to kill a couple of the herders, either by throwing them to the Slogs or off the edge of the level; there are enough dotted around the place to open the entrance to the cave. It’s easy to throw a Meep over the wall, too. In fact, you could in theory throw the whole Meep herd (except one) into the Glukkon’s office.
