No need to go around your a$$ to scratch your elbow. Remember KISS.
If that pebble is in there, it mostly is under the primary gear on the right side. There is even a baffle under the oil filler hole anyway. It shouldn't be too far away.
I'd recommend draining the oil by removing the cover. Not by the drain plug. Just to make sure the oil doesn't push it any further.
Good luck.
