Kalw watched, they were eating now, well distracted by their own needs, and they were in a very good spot, this was it, he'd cause the chaos, break one away, and have his meal. He shoved some of the larger rocks, which got the very tiny ones rolling, causing them to roll larger ones along, et cetera. Klaw looked down, it was a very nice rock slide, headed straight for those unsuspecting pokemon, yes, he'd wait for the the chaos to ensue before attacking, but first, enjoy the show.
