As a matter of fact, it didn't really hurt worth mentioning, otherwise Merlin probably wouldn't have been tolerating this kind of behavior at all. Or perhaps more accurately, Merlin's used to much worse roughhousing and is a fair bit tougher than his flowery appearance might suggest, so it doesn't particularly bother him.

"Ah, well, if Cath Palug ever found out, he'd be quite annoyed!" Merlin replies, evidently assuming that it was 'the second' part of the name causing the confusion.

Of course, that begs the quest of who/what the original Cath Palug is, but he doesn't seem particularly inclined to volunteer that!

In any case the creature--Cath Palug II--looks over when she calls out to it. It's still a bit shy or wary, but it does recognize the food being offered now, so after a moment of a slow, cautious approach, it quickly nabs the morsel and then scurries off again to eat it.
