Mythical Creatures/Folk (Spoilers ALL Books, including Words Like Coins)

[Farseer]

More than a few times I have raised the issue about Fool's ability to slip in and out of a room unnoticed (even a supposedly locked one at times), not to mention an ability to bypass Fitz' Wit-sense. I have also often mentioned that Pecksies and Fool share some similarities, and it seems that this ability to come and go is one of them, going on the example in this paragraph (at least I thought of Fool the very first time I read it!!):

The door to the room was still shut. "How did you get in here?" Mirrifen's voice shook slightly.

"By a way no rat could come..."

One of the many examples of Fool doing this would be in FE when he, Fitz and Dutiful are making their way back to Buckkeep. Fitz latched the inn room door and went to sleep, only to find Fool there in bed the next morning (I loved that Fitz was surprised to see that Fool had not stayed with Laurel and Fool was just as surprised/pleased to see that Fitz had not stayed with Starling!! ).

'I didn't expect to see you in your bed this morning,' I greeted him, and then, 'How did you get in? I latched that door last night.'

'Did you? Interesting. But you can scarcely be more surprised to see me in my own bed than I am to see you in yours.'

So, is this all magical or is it simply that Pecksies and Fool share some latent and stealthy 'break and enter' talents?
