Despite his scepticism for her ability to grant a wish, Emet-Selch has nothing but time on his hands for the moment. He can be found bent over at various places trying to find the strange, fluffy creatures. If you're lucky(?) you might see him chasing one down as it hop, skips, and glitches out of his reach.

"Come back here, you damned things!" he curses as another slips through his grasp at the last possible moment.

Maybe a subtler approach is called for. A baited trap perhaps?
